Allah's Apostle used to say very often in bowing and prostration (during his prayers), Subhanka Allahumma Rabbana wa bihamdika; Allahumma ighfirli," according to the order of the Qur'an.

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.

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 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.'

Whenever the Prophet went to the lavatory, he used to say: "Allahumma inni a`udhu bika min al-khubuthi wal khaba'ith."

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.)"

We came with Allah's Apostle (to Mecca) and we were saying: 'Labbaika Allahumma Labbaik' for Hajj. Allah's Apostle ordered us to perform `Umra with that Ihram (instead of Hajj).

I know how the Prophet used to say (Talbiya) and it was: 'Labbaika Allahumma Labbaik, Labbaika la sharika Laka labbaik, Inna-l-hamda wan-ni'mata Laka walmu Lk, La sharika Laka'.

Allah's Apostle said, "When the Imam says, "Sami`a l-lahu liman hamidah," you should say, "Allahumma Rabbana laka l-hamd." And if the saying of any one of you coincides with that of the angels, all his past sins will be forgiven."

The Prophet said to me, "Whenever you go to bed perform ablution like that for the prayer, lie or your right side and say, "Allahumma aslamtu wajhi ilaika, wa fauwadtu `Amri ilaika, wa alja'tu Zahri ilaika raghbatan wa rahbatan ilaika. La Malja'a wa la manja minka illa ilaika. Allahumma amantu bikitabika-l-ladhi anzalta wa bina-biyika-l ladhi arsalta" (O Allah! I surrender to You and entrust all my affairs to You and depend upon You for Your Blessings both with hope and fear of You. There is no fleeing from You, and there is no place of protection and safety except with You O Allah! I believe in Your Book (the Qur'an) which You have revealed and in Your Prophet (Muhammad) whom You have sent). Then if you die on that very night, you will die with faith (i.e. or the religion of Islam). Let the aforesaid words be your last utterance (before sleep)." I repeated it before the Prophet and when I reached "Allahumma amantu bikitabika-l-ladhi anzalta (O Allah I believe in Your Book which You have revealed)." I said, "Wa-rasulika (and your Apostle)." The Prophet said, "No, (but say): 'Wanabiyika-l-ladhi arsalta (Your Prophet whom You have sent), instead."

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."

The Prophet used to say in his bowing and prostrations, "Subhanaka l-lahumma Rabbana wa bihamdika; Allahumma ghfir li.' (Exalted [from unbecoming attributes] Are you O Allah our Lord, and by Your praise [do I exalt you]. O Allah! Forgive me).

It was said, "O Allah's Apostle! We know how to greet you, but how to invoke Allah for you?" The Prophet said, "Say: Allahumma salli ala Muhammadin wa'ala `Ali Muhammaddin, kama sallaita 'ala all Ibrahim, innaka Hamidun Majid."
