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.'

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).

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."

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

When the Prophet went to bed, he would say: "Bismika amutu wa ahya." and when he got up he would say:" Al-hamdu li l-lahil-ladhi ahyana ba'da ma amatana wa ilaihin-nushur."

Whenever the Prophet lay on his bed, he used to say: "Allahumma bismika amutu wa ahya," and when he woke up he would say: "Al-hamdu lil-lahilladhi ahyana ba'da ma an atana, wa ilaihi an-nushur."

When the Prophet went to bed, he used to say, "Allahumma bismika ahya wa amut." And when he woke up in the mornings he used to say, "Al-hamdu li l-lahi al-ladhi ahyana ba'da ma amatana wa ilaihi-nnushur."

When the Prophet went to bed at night, he used to say: "Bismika namutu wa nahya." And when he got up in the morning, he used to say, "Al hamdu li l-lahi al-ladhi ahyana ba'da ma amatana, wa ilaihi-nnushur."

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, "If anyone of you, when having sexual intercourse with his wife, says: Bismillah, Allahumma jannibni-Sh-Shaitan wa jannib-ish-Shaitan ma razaqtana, and if it is destined that they should have a child, then Satan will never be able to harm him."

The Prophet said, "The most superior way of asking for forgiveness from Allah is: 'Allahumma anta Rabbi la ilaha illa anta. Khalaqtani wa ana `Abduka, wa ana 'ala 'ahdika wa Wa'dika mastata'tu abu'u Laka bi ni 'matika wa abu'u Laka bidhanbi; faghfirli fa'innahu la yaghfiru-dh-dhunuba ill a ant a. A'uidhu bika min sharri ma sana'tu.' If somebody recites this invocation during the night, and if he should die then, he will go to Paradise (or he will be from the people of Paradise). And if he recites it in the morning, and if he should die on the same day, he will have the same fate."

Allah's Apostle said, "If anyone of you, when intending to have a sexual relation (sleep) with his wife, says: Bismillah, Allahumma jannibna ashShaitan, wa Jannib ash-Shaitana ma razaqtana, Satan would never harm that child, should it be ordained that they will have one. (Because of that sleep).

Whenever the Prophet intended to go to bed, he would recite: "Bismika Allahumma amutu wa ahya (With Your name, O Allah, I die and I live)." And when he woke up from his sleep, he would say: "Al-hamdu lil-lahil-ladhi ahyana ba'da ma amatana; wa ilaihi an-nushur (All the Praises are for Allah Who has made us alive after He made us die (sleep) and unto Him is the Resurrection). "

Yahya related to me from Malik from Summayy, the mawla of Abu Bakr from al-Qa'qa ibn Hakim that Kab al-Ahbar said, "Had it not been for some words which I said, the jews would have made me into a donkey." Someone asked him what they were. He said, "I seek refuge with the immense Face of Allah - there is nothing greater than it - and with the complete words of Allah which neither the good person nor the corrupt can exceed and with all the most beautiful names of Allah, what I know of them and what I do not know, from the evil of what He has created and originated and multiplied."

Audhu bi wajhi'llahi l-adheem aladhee laysa shay'un adham minh, wa bi kalimati'llahi't-tammati, alatee la yujawizu hunna barra wa la fajir, wa bi asma'illahi'l-husna kulliha ma alamtu minha wa ma lam alam, min sharri ma khalaqa wa bara'a wa dhara'a.

The Prophet said, "If anyone of you, when intending to have a sexual intercourse with his wife, says: 'Bismillah, Allahumma jannibna-sh-shaitan, wa jannibi-sh-shaitan ma razaqtana,' and if the couple are destined to have a child (out of that very sexual relation), then Satan will never be able to harm that child."
