the Messenger of Allah (saas) said to a man: "What do you say during your prayer?" He said: "I recite the Tashah-hud then I ask for Allah for Paradise and see refuge with Him from Hell, but by Allah I do not understand your whispering or the whispering of Mu'adh." He said: "It is concerning them (Paradise and Hell) that we are whispering."

"The Messenger of Allah (saas) used to teach us this supplication just as he would teach us a Surah from the Qur'an: 'Allahumma inni a'udhu bika min 'adhabi jahannam, wa a'udhu bika min 'adhabil-qabr, wa a'udhu bika min fitnatil-masihil-dajjal, wa a'udhu bika min fitnatil-mahya wal-mamat (O Allah, I seek refuge with You from the torment of Hell, and I seek refuge with You from the torment of the grave, and I see refuge with you from the tribulation of False Christ, and I seek refuge with You from the trials of life and death).'"

'Allahumma! Inni a'udhu bika minal-arba': min 'ilmin la yanfa'u, wa min qalbin la yakhsha'u, wa min nafsin la tashba'u, wa min du'a'in la yusma' [O Allah, I seek refuge with You from four things: From knowledge that is of no benefit, from a heart that does not fear (You), from a soul that is never satisfied, and from a supplication that is not heard].'"

"The Messenger of Allah (saas) came out to us, leaning on a stick, and when we saw him we stood up. He said: 'Do not do what the Persians do for their leaders.' We said: 'O Messenger of Allah, why don't you pray to Allah for us?' He said: 'Allahummaghfirlana, warhamna, warda 'anna, wa taqabbal minna, wa adkhilnal-jannah, wa najjina minan-nar, wa aslih lana sha'nana kullah. [O Allah, forgive us and have mercy on us, be pleased with us and accept (our good deeds) from us, admit us to Paradise and save us from Hell, and rectify all our affairs].' It was as if we wanted him to say more, but he said: 'Have I not summed everything for you?'"

he said to the Messenger of Allah (saas): "Teach me a supplication which I can say during my prayer." He said: "Say: Allahumma inni zalamtu nafsi zulman kathiran wa la yaghfirudh-dhunub illa Anta, faghfirli maghfiratan min 'indika warhamni, innaka Antal-Ghafurur-Rahim (O Allah, I have wronged myself greatly and no one forgives sins but You, so grant me forgiveness from You and have mercy on me, for You are the Oft-Forgiving, Most Merciful)."

"The Messenger of Allah (saas) often used to say: 'Allahumma thabbit qalbi 'ala dinika [O Allah, make my heart steadfast in (adhering to) Your religion].' A man said: 'O Messenger of Allah! Do you fear for us when we have believed in you and in (the Message) that you have brought?' He said: 'Hearts are between two of the fingers of the Most Merciful, and He controls them.'" (Hasan)Al-A'mash (one of the narrators) indicated with his fingers.

"The Messenger of Allah (saas) used to say: 'Allahummanfa'ni bima 'allamtani, wa 'allimni ma yanfa'uni, wa zidni 'ilman, wal-hamdu lillahi 'ala kulli hal, wa a'udhu billahi min 'adhabin-nar (O Allah, benefit me by that which You have taught me, and teach me that which will benefit me, and increase me in knowledge. Praise is to Allah in all situations, and I seek refuge with Allah from the torment of the Fire).'"

the Messenger of Allah (saas) said: "Indeed the supplication is the worship." Then he recited: "And your Lord said: Invoke Me, I will respond to you."

“Subhan Allahi Rabbil-‘alamin (Glory is to Allah, the Lord of the worlds),” repeating that for a while, then he said: Subhan Allahi wa bihamdihi (Glory and praise is to Allah).”

“Allahumma inna na’udhu bika min sharri ma ursila bihi (O Allah, we seek refuge with You from the evil of that with which it is sent).” Then if it rained he would say: “Allahumma sayyiban nafi’an (O Allah, a beneficial rain),” two or three times. And if Allah dispelled it and it did not rain, he would praise Allah for that.

“Allahumma aj’alhu sayyiban hani’an (O Allah, make it a wholesome rain cloud).”

his father said: "The Messenger of Allah (saas) said: 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 bi ni'matika wa abu'u bi dhanbi faghfirli, fa innahu la yaghfirudh-dhunuba illa Anta (O Allah, You are my Lord, there is none worthy of worship except You. You have created me and I am Your slave, and I am adhering to Your covenant and Your promise as much as I can. I seek refuge with You from the evil of what I do. I acknowledge Your blessing and I acknowledge my sin, so forgive me, for there is none who can forgive sin except You)."He said: "The Messenger of Allah (saas) said: 'Whoever says this by day and by night, if he dies that day or that night, he will enter Paradise if Allah wills."

the Messenger of Allah (saas) said: "There are three supplications that will undoubtedly be answered: the supplication of one who has been wronged; the supplication of the traveler; and the supplication of a father for his child."
