I gave the pledge of allegiance to Allah's Apostle for the following:

1. offer prayers perfectly

2. pay the Zakat (obligatory charity)

3. and be sincere and true to every Muslim.

The Prophet said "The most superior way of asking for forgiveness from Allah is: O Allah, You are my Lord, there is none worthy of worship except You. You have created me, and I am Your servant, and I am faithful to Your covenant and promise as much as I can. I seek refuge in You from the evil of what I have done. I acknowledge Your blessings upon me, and I admit my sins. So forgive me, for none forgives sins except You.
(Allahumma anta Rabbi la ilaha illa anta, Khalaqtani wa ana `Abduka, wa ana `ala `ahdika wa wa`dika mastata`tu, A`udhu bika min Sharri ma sana`tu, abu'u Laka bini`matika `alaiya, wa abu'u laka bidhanbi faghfir lee fa innahu la yaghfiru adhdhunuba illa anta) "
The Prophet added. "If somebody recites it during the day with firm faith in it, and dies on the same day before the evening, he will be from the people of Paradise; and if somebody recites it at night with firm faith in it, and dies before the morning, he will be from the people of Paradise."

(the clerk of Al-Mughira bin Shu`ba) Once Al-Mughira dictated to me in a letter addressed to Muawiya that the Prophet used to say after every compulsory prayer, "La ilaha illa l-lahu wahdahu la sharika lahu, lahu l-mulku wa lahu l-hamdu, wa huwa `ala kulli shay'in qadir. Allahumma la mani`a lima a`taita, wa la mu`tiya lima mana`ta, wa la yanfa`u dhal-jaddi minka l-jadd. [There is no Deity but Allah, Alone, no Partner to Him. His is the Kingdom and all praise, and Omnipotent is he. O Allah! Nobody can hold back what you gave, nobody can give what You held back, and no struggler's effort can benefit against You]." And Al-Hasan said, "Al-jadd' means prosperity [??]."

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."

We used to say the greeting, name and greet each other in the prayer. Allah's Apostle heard it and said:--"Say, 'at-tahiyyatu lil-lahi was-salawatu wat-taiyibatu . Assalamu 'Alaika aiyuha-n-Nabiyu warahmatu- l-lahi wa-barakatuhu. _ Assalamu alaina wa-'ala 'ibadi-l-lahi as-salihin.. Ashhadu an la ilaha illa-l-lah wa ashhadu anna Muhammadan `Abdu hu wa Rasuluh. (All the compliments are for Allah and all the prayers and all the good things (are for Allah). Peace be on you, O Prophet, and Allah's mercy and blessings (are on you). And peace be on us and on the good (pious) worshipers of Allah. I testify that none has the right to be worshipped but Allah and that Muhammad is His slave and Apostle.) So, when you have said this, then you have surely sent the greetings to every good (pious) worshipper of Allah, whether he be in the Heaven or on the Earth . "

When the Prophet went to bed at night, he would put his hand under his cheek and then say, "Allahumma bismika amutu wa ahya," and when he got up, he would say, "Al-Hamdu lil-lahi al-ladhi ahyana ba'da ma amatana, wa ilaihi an-nushur."

The Prophet said, "When anyone of you goes to bed, he should dust it off thrice with the edge of his garment, and say: Bismika Rabbi Wada`tu janbi, wa bika arfa'hu. In amsakta nafsi faghfir laha, wa in arsaltaha fahfazha bima tahfaz bihi 'ibadaka-s-salihin."

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.)"

My friend (the Prophet ) advised me to observe three things: (1) to fast three days a month; (2) to pray two rak`at of Duha prayer (forenoon prayer); and (3) to pray witr before sleeping.

(the wife of the Prophet) Allah's Apostle used to invoke Allah in the prayer saying "Allahumma inni a`udhu bika min `adhabi l-qabr, wa a`udhu bika min fitnati l-masihi d-dajjal, wa a`udhu bika min fitnati l-mahya wa fitnati l-mamat. Allahumma inni a`udhu bika mina l-ma'thami wa l-maghram. (O Allah, I seek refuge with You from the punishment of the grave, from the afflictions of the imposter- Messiah, and from the afflictions of life and death. O Allah, I seek refuge with You from sins and from debt)." Somebody said to him, "Why do you so frequently seek refuge with Allah from being in debt?" The Prophet replied, "A person in debt tells lies whenever he speaks, and breaks promises whenever he makes (them)." `Aisha also narrated: I heard Allah's Apostle in his prayer seeking refuge with Allah from the afflictions of Ad-Dajjal.

Allah's Apostle said, "The signs of a hypocrite are three: (1) whenever he speaks, he tells a lie, (2) whenever he is entrusted, he proves to be dishonest, (3) whenever he promises, he breaks his promise.

A man asked the Prophet "What deeds are the best?" The Prophet said: "(1) To perform the (daily compulsory) prayers at their (early) stated fixed times, (2) to be good and dutiful to one's own parents, (3) and to participate in Jihad in Allah's Cause."

The Prophet said, "When anyone of you go to bed, he should shake out his bed with the inside of his waist sheet, for he does not know what has come on to it after him, and then he should say: 'Bismika Rabbi Wada`tu Janbi wa bika arfa'uhu, In amsakta nafsi farhamha wa in arsaltaha fahfazha bima tahfazu bihi ibadakas-salihin."

The Prophet was asked about the great sins He said, "They are:-- (1 ) To join others in worship with Allah, (2) To be undutiful to one's parents. (3) To kill a person (which Allah has forbidden to kill) (i.e. to commit the crime of murdering). (4) And to give a false witness."

The Prophet said, "The biggest of Al-Ka`ba'ir (the great sins) are (1) to join others as partners in worship with Allah, (2) to murder a human being, (3) to be undutiful to one's parents (4) and to make a false statement," or said, "to give a false witness."

Allah's Apostle said, "From among the portents of the Hour are (the following): -1. Religious knowledge will be taken away (by the death of Religious learned men). -2. (Religious) ignorance will prevail. -3. Drinking of Alcoholic drinks (will be very common). -4. There will be prevalence of open illegal sexual intercourse.
