The Prophet (saws) said: The best number of companions is four, the best number in expeditions four hundred, and the best number in armies four thousand; and twelve thousand will not be overcome through smallness of numbers.

Abu Dawud said: What is correct is that this tradition is mursal (i.e. the link of the Companion is missing).

A hadith like this has been narrated on the authority of Humaid with the same chain of transmitters.

The Prophet was on a journey and recited in one of the first two rak`at of the `Isha' prayer "Wa t-teeni wa z-zaitun." (95)

When we prayed with the Prophet we used to say: As-Salam be on Allah from His worshipers, As- Salam be on Gabriel, As-Salam be on Michael, As-Salam be on so-and-so. When the Prophet finished his prayer, he faced us and said, "Allah Himself is As-Salam (Peace), so when one sits in the prayer, one should say, 'at-Tahiyatu-li l-lahi Was-Salawatu, Wat-Taiyibatu, As-Salamu 'Alaika aiyuhan- Nabiyyu wa Rah-matul-iahi wa Barakatuhu, As-Salamu 'Alaina wa 'ala 'Ibadillahi assalihin, for if he says so, then it will be for all the pious slave of Allah in the Heavens and the Earth. (Then he should say), 'Ash-hadu an la ilaha illalllahu wa ash-hadu anna Muhammadan `Abduhu wa rasulu-hu,' and then he can choose whatever speech (i.e. invocation) he wishes " (See Hadith No. 797, Vol. 1).

The Prophet used to invoke Allah with the following invocation: 'Rabbi-ghfir-li Khati 'ati wa jahli wa israfi fi `Amri kullihi, wa ma anta a'lamu bihi minni. Allahumma ighfirli khatayaya wa 'amdi, wa jahli wa jiddi, wa kullu dhalika'indi. Allahumma ighrifli ma qaddamtu wa ma akhartu wa ma asrartu wa ma a'lantu. Anta-l-muqaddimu wa anta-l-mu'akh-khiru, wa anta 'ala kulli shai'in qadir.'

Allah's Apostle said," Whoever says: "La ilaha illal-lah wahdahu la sharika lahu, lahu-l-mulk wa lahul- hamd wa huwa 'ala kulli shai'in qadir," one hundred times will get the same reward as given for manumitting ten slaves; and one hundred good deeds will be written in his accounts, and one hundred sins will be deducted from his accounts, and it (his saying) will be a shield for him from Satan on that day till night, and nobody will be able to do a better deed except the one who does more than he."

When the Prophet got up at night to offer the night prayer, he used to say: "Allahumma laka l-hamdu; Anta nuras-samawati wal ardi wa man fihinna. wa laka l-hamdu; Anta qaiyim as-samawati wal ardi wa man flhinna. Wa lakaI-hamdu; Anta-l-,haqqun, wa wa'daka haqqun, wa qauluka haqqun, wa liqauka haqqun, wal-jannatu haqqun, wannaru haqqun, was-sa atu haqqun, wan-nabiyyuna huqqun, Mahammadun haqqun, Allahumma laka aslamtu, wa Alaika tawakkaltu, wa bika amantu, wa ilaika anabtu, wa bika Khasamtu, wa ilaika hakamtu, faghfirli ma qaddamtu wa ma akh-khartu, wa ma asrartu, wa ma a'lantu. Anta al-muqaddimu, wa anta al-mu-'akhkhiru. La ilaha il-la anta (or La ilaha ghairuka)"

The Prophet used to invoke Allah, saying, "Allahumma ighfirli khati'ati wa jahli wa israfi fi `Amri, wa ma anta a-'lamu bihi minni. Allahumma ighfirli hazali wa jiddi wa khata'i wa amdi, wa kullu dhalika 'indi."

The Prophet (p.b.u.h) used to teach us the way of doing Istikhara (Istikhara means to ask Allah to guide one to the right sort of action concerning any job or a deed), in all matters as he taught us the Suras of the Qur'an. He said, "If anyone of you thinks of doing any job he should offer a two rak`at prayer other than the compulsory ones and say (after the prayer): -- 'Allahumma inni astakhiruka bi'ilmika, Wa astaqdiruka bi-qudratika, Wa as'alaka min fadlika Al-`azlm Fa-innaka taqdiru Wala aqdiru, Wa ta'lamu Wala a'lamu, Wa anta 'allamu l-ghuyub. Allahumma, in kunta ta'lam anna hadha-lamra Khairun li fi dini wa ma'ashi wa'aqibati `Amri (or 'ajili `Amri wa'ajilihi) Faqdirhu wa yas-sirhu li thumma barik li Fihi, Wa in kunta ta'lamu anna hadha-lamra shar-run li fi dini wa ma'ashi wa'aqibati `Amri (or fi'ajili `Amri wa ajilihi) Fasrifhu anni was-rifni anhu. Waqdir li al-khaira haithu kana Thumma ardini bihi.' (O Allah! I ask guidance from Your knowledge, And Power from Your Might and I ask for Your great blessings. You are capable and I am not. You know and I do not and You know the unseen. O Allah! If You know that this job is good for my religion and my subsistence and in my Hereafter--(or said: If it is better for my present and later needs)--Then You ordain it for me and make it easy for me to get, And then bless me in it, and if You know that this job is harmful to me In my religion and subsistence and in the Hereafter--(or said: If it is worse for my present and later needs)--Then keep it away from me and let me be away from it. And ordain for me whatever is good for me, And make me satisfied with it). The Prophet added that then the person should name (mention) his need.

Another chain reports a similar hadith.

When the Prophet got up at night to offer the Tahajjud prayer, he used to say: Allahumma lakal-hamd. Anta qaiyyimus-samawati wal-ard wa man fihinna. Walakal-hamd, Laka mulkus-samawati wal-ard wa man fihinna. Walakal-hamd, anta nurus-samawati wal-ard. Wa lakal-hamd, anta-l-haq wa wa'duka-lhaq, wa liqa'uka Haq, wa qauluka Haq, wal-jannatu Han wan-naru Haq wannabiyuna Haq. Wa Muhammadun, sallal-lahu'alaihi wasallam, Haq, was-sa'atu Haq. Allahumma aslamtu Laka wabika amantu, wa 'Alaika tawakkaltu, wa ilaika anabtu wa bika khasamtu, wa ilaika hakamtu faghfir li ma qaddamtu wama akh-khartu wama as-rartu wama'a lantu, anta-l-muqaddim wa anta-l-mu akh-khir, la ilaha illa anta (or la ilaha ghairuka). (O Allah! All the praises are for you, You are the Holder of the Heavens and the Earth, And whatever is in them. All the praises are for You; You have the possession of the Heavens and the Earth And whatever is in them. All the praises are for You; You are the Light of the Heavens and the Earth And all the praises are for You; You are the King of the Heavens and the Earth; And all the praises are for You; You are the Truth and Your Promise is the truth, And to meet You is true, Your Word is the truth And Paradise is true And Hell is true And all the Prophets (Peace be upon them) are true; And Muhammad is true, And the Day of Resurrection is true. O Allah ! I surrender (my will) to You; I believe in You and depend on You. And repent to You, And with Your help I argue (with my opponents, the non-believers) And I take You as a judge (to judge between us). Please forgive me my previous And future sins; And whatever I concealed or revealed And You are the One who make (some people) forward And (some) backward. There is none to be worshipped but you . Sufyan said that `Abdul Karim Abu Umaiya added to the above, 'Wala haula Wala quwata illa billah' (There is neither might nor power except with Allah).

The Prophet used to teach us the Istikhara for each and every matter as he used to teach us the Suras from the Holy Qur'an. (He used to say), "If anyone of you intends to do something, he should offer a two-rak`at prayer other than the obligatory prayer, and then say: 'Allahumma inni astakhiruka bi'ilmika, wa astaqdiruka biqudratika, wa as'aluka min fadlika-l-'azim, fa innaka taqdiru wala aqdiru, wa ta'lamu wala a'lamu, wa anta'allamu-l-ghuyub. Allahumma in kunta ta'lamu anna hadha-lamra khairun li fi dini wa ma'ashi wa 'aqibati `Amri (or said, fi 'ajili `Amri wa ajilihi) fa-qdurhu li, Wa in kunta ta'lamu anna ha-dha-l-amra sharrun li fi dini wa ma'ashi wa 'aqibati `Amri (or said, fi ajili `Amri wa ajilihi) fasrifhu 'anni was-rifni 'anhu wa aqdur li alkhaira haithu kana, thumma Raddani bihi," Then he should mention his matter (need).

The Prophet "Whoever gets up at night and says: -- 'La ilaha il-lallah Wahdahu la Sharika lahu Lahu-lmulk, waLahu-l-hamd wahuwa 'ala kullishai'in Qadir. Al hamdu lil-lahi wa subhanal-lahi wa la-ilaha il-lal-lah wa-l-lahu akbar wa la hawla Wala Quwata il-la-bil-lah.' (None has the right to be worshipped but Allah. He is the Only One and has no partners . For Him is the Kingdom and all the praises are due for Him. He is Omnipotent. All the praises are for Allah. All the glories are for Allah. And none has the right to be worshipped but Allah, And Allah is Great And there is neither Might nor Power Except with Allah). And then says: -- Allahumma, Ighfir li (O Allah! Forgive me). Or invokes (Allah), he will be responded to and if he performs ablution (and prays), his prayer will be accepted."

The people said, "O Allah's Apostle ! How may we send Salat on you?" He said, "Say: Allahumma Salli 'ala- Muhammadin wa azwajihi wa dhurriyyatihi kama sal-laita 'ala `Ali Ibrahim; wa barik 'ala Muhammadin wa azwajihi wa dhurriyyatihi kamabarakta 'ala `Ali Ibrahim innaka hamidun majid."

Allah's Apostle said, "Whoever says, 'Subhan Allah wa bihamdihi,' one hundred times a day, will be forgiven all his sins even if they were as much as the foam of the sea.

That the Prophet advised a man, saying, "If you intend to lie down (i.e. go to bed), say, 'Allahumma aslamtu nafsi ilaika wa fauwadtu `Amri ilaika, wa wajjahtu wajhi ilaika wa alja'tu zahri ilaika, reghbatan wa rahbatan ilaika. La malja'a wa la manja minka illa ilaika. Amantu bikitabikal-ladhi anzalta; wa nabiyyikalladhi arsalta.' And if you should die then (after reciting this before going to bed) you will die on the religion of Islam"

Allah's Apostle used to keep silent between the Takbir and the recitation of Qur'an and that interval of silence used to be a short one. I said to the Prophet "May my parents be sacrificed for you! What do you say in the pause between Takbir and recitation?" The Prophet said, "I say, 'Allahumma, baa`id baini wa baina khatayaya kama baa`adta baina l-mashriqi wa l-maghrib. Allahumma, naqqini min khatayaya kama yunaqqa th-thawbu l-abyadu mina d-danas. Allahumma, ighsil khatayaya bi l-maa'i wa th-thalji wa l-barad (O Allah! Set me apart from my sins (faults) as the East and West are set apart from each other and clean me from sins as a white garment is cleaned of dirt (after thorough washing). O Allah! Wash off my sins with water, snow and hail.)"

One night I slept at the house of Maimuna. The Prophet woke up, answered the call of nature, washed his face and hands, and then slept. He got up (late at night), went to a water skin, opened the mouth thereof and performed ablution not using much water, yet he washed all the parts properly and then offered the prayer. I got up and straightened my back in order that the Prophet might not feel that I was watching him, and then I performed the ablution, and when he got up to offer the prayer, I stood on his left. He caught hold of my ear and brought me over to his right side. He offered thirteen rak`at in all and then lay down and slept till he started blowing out his breath as he used to do when he slept. In the meantime Bilal informed the Prophet of the approaching time for the (Fajr) prayer, and the Prophet offered the Fajr (Morning) prayer without performing new ablution. He used to say in his invocation, Allahumma ij`al fi qalbi nuran wa fi basari nuran, wa fi sam`i nuran, wa`an yamini nuran, wa`an yasari nuran, wa fawqi nuran, wa tahti nuran, wa amami nuran, wa khalfi nuran, waj`al li nuran." Kuraib (a sub narrator) said, "I have forgotten seven other words, (which the Prophet mentioned in this invocation). I met a man from the offspring of Al-`Abbas and he narrated those seven things to me, mentioning, '(Let there be light in) my nerves, my flesh, my blood, my hair and my body,' and he also mentioned two other things."

When we prayed with the Prophet we used to say, "Peace be on Allah from His slaves and peace be on so and so." The Prophet said, "Don't say As-Salam be on Allah, for He Himself is As-Salam, but say, at-tahiyatu li l-lahi wa s-salawatu wa t-taiyibat. As-salamu `alaika aiyuha n-Nabiyu wa rahmatu l-lahi wa barakatuh. As-salamu `alaina wa `ala `ibadi l-lahi s-salihin. (If you say this then it will reach all the slaves in heaven or between heaven and earth). Ash-hadu al la-ilaha illa l-lah, wa ash-hadu anna Muhammadan `Abduhu wa Rasuluh.' Then select the invocation you like best and recite it." (See Hadith No. 794, 795 & 796).

When Allah's Apostle went to bed, he used to sleep on his right side and then say, "All-ahumma aslamtu nafsi ilaika, wa wajjahtu wajhi ilaika, wa fauwadtu `Amri ilaika, wa alja'tu zahri ilaika, raghbatan wa rahbatan ilaika. La Malja'a wa la manja minka illa ilaika. Amantu bikitabika al-ladhi anzalta wa nabiyyika al-ladhi arsalta! Allah's Apostle said, "Whoever recites these words (before going to bed) and dies the same night, he will die on the Islamic religion (as a Muslim).

We used to pray behind the Prophet and used to say: "As-Salamu 'Al-Allah. The Prophet said, "Allah himself is As-Salam (Name of Allah), so you should say: 'at-Tahiyatu lil-lahi was-sala-watu wattaiyibatu, as-salamu `alaika aiyyuha-n-nabiyyu wa rahmatu-l-lahi wa barakatuhu, as-salamu `alaina wa `ala `ibadi-l-lahi as-salihin. Ashhadu an la ilaha il-lallah, wa ash-hadu anna Muhammadan `abduhu wa rasuluhu."'
