Abu Huraira reported God’s messenger as stating that God has said, “If anyone is hostile to a friend of mine, I have declared war against him. No one draws near to me with anything dearer to me than what I have made obligatory for him. If my servant keeps drawing near to me with supererogatory acts I shall love him, and when I love him I shall be his hearing with which he hears, his sight with which he sees, his hand with which he grasps and his foot with which he walks. If he asks from me I shall certainly give him and if he seeks refuge in me I shall certainly give him refuge. I have not hesitated about anything I do as I hesitate about taking the soul of a believer who dislikes death, for I dislike grieving him, but he cannot escape it.” Bukhari transmitted it.

Abud Darda’ reported God's messenger as saying, “Would you like me to tell you the best and purest of your deeds in the estimation of your King, those which raise your degrees highest, those which are better for you than spending gold and silver, and are better for you than that you should meet your enemy and cut off one another's head?” On receiving a reply in the affirmative he said, “It is remembering God.” Malik, Ahmad, Tirmidhi and Ibn Majah transmitted it, but Malik traced it no farther back than Abud Darda’.

‘Abdallah b. Busr told of a desert Arab coming to the Prophet and asking who was best among men, to which he replied, “Happy is he whose life is long and whose deeds are good.” He asked God’s messenger what deed was most excellent, and he replied, “That you should leave the world with the mention of God fresh on your tongue.” Ahmad and Tirmidhi transmitted it.

Mu'adh b. Jabal said, “A man does nothing more calculated to rescue him from God’s punishment than making mention of God.” Malik, Tirmidhi and Ibn Majah transmitted it.

Abu Huraira reported God's messenger as stating that God says, "I am with my servant when he remembers me and his lips move making mention of me." Bukhari transmitted it.

Abu Huraira reported God’s messenger as saying, “God Most High has ninety-nine names. He who retains them in his memory will enter paradise.

Buraida told that God’s messenger heard a man saying, “O God I ask Thee by virtue of Thy being God than whom there is no god, the One, He to whom men repair, who has not begotten and has not been begotten, and to whom no one is equal,” and said, “He has supplicated God using His greatest name, when asked by which He gives and when supplicated by which He answers.” Tirmidhi and Abu Dawud transmitted it.

Anas said that when he was sitting with the Prophet in the mosque a man who was praying said, “O God, I ask Thee by virtue of the fact that praise is due to Thee than whom there is no god, who showest favour and beneficence, the Originator of the heavens and the earth, O Lord of Majesty and Splendour, O Living One; O Eternal One, I ask of Thee.” The Prophet then said, “He has supplicated God using His greatest name, when supplicated by which He answers and when asked by which He gives.” Tirmidhi, Abu Dawud, Nasa’i and Ibn Majah transmitted it.

Asma’ daughter of Yazid reported the Prophet as saying, “God’s greatest name is in these two verses, ‘And your God is one God; there is no god but He, the Compassionate, the Merciful’ [Qur'an, ii, 163.], and the beginning of Al 'Imran, ‘A.L.M. God, there is no god but He, the Living, the Eternal’ [Qur'an, iii. 1.]” Tirmidhi, Abu Dawud, Ibn Majah and Darimi transmitted it.

“There is no god but Thee to whom be the glory. I was indeed a wrongdoer.” [Qur'an, xxi, 87]Ahmad and Tirmidhi transmitted it.

Buraida said that once when he entered the mosque with God’s messenger at the time of the evening prayer a man was reciting with a loud voice, so he asked God’s messenger whether he thought the man was hypocritical, but he replied’ “No, he is a penitent believer.” He said that Abu Musa al-Ash‘ari was [also]* reciting in a loud voice, and God’s messenger began to listen to his recitation. Afterwards Abu Musa sat down and engaged in supplication saying, “O God, I call Thee to witness that Thou art God than whom there is no god, One, to whom men repair, who hast not begotten and hast not been begotten, and to whom no one is equal.” God’s messenger then said, “He has asked God using His name when asked by which He gives, and when supplicated by which He answers.” Buraida asked God’s messenger whether he should tell him what he had heard him say, and when he agreed he told him what God’s messenger had said, and Abu Musa said to him, “Today you are a true brother to me, having told me the words of God’s messenger.” *This word is not in the text, but Mirqat explains that it must be understood as Abu Musa as not the man referred to above.Razin transmitted it.

He reported God’s messenger as. saying, “O God, I have entered into a covenant with Thee which Thou wilt not break. I am only a human being, so when I have injured, reviled, cursed or beaten a believer, make that for him a mercy, a purification and a means by which Thou wilt bring him near to Thee on the day of resurrection.”(Bukhari and Muslim.)

He reported God’s messenger as saying, “A servant is granted an answer provided he does not ask for anything sinful or for breaking ties of relationship, and provided he does not demand an answer quickly.” On being asked what demanding an answer quickly meant, God’s messenger replied, “It is when he says he has prayed and prayed and does not think he will be answered, so he grows weary in such circumstances and gives up supplication.” Muslim transmitted it.

I asked the Prophet’s permission to perform an ‘umra and he gave me permission, saying, “Include me in your supplication, little brother, and do not forget me.” Then he said a word to me for which I would not be willing to take the world in exchange. Abu Dawud and Tirmidhi transmitted it, Tirmidhi’s version ending with “do not forget me.”

one who has just ended a fast, a just imam, and one who has been wronged whose supplication is raised by God above the clouds and for which the gates of heaven are opened. The Lord says, ‘I swear by my might that I will certainly help you, though it be after some time’.” Tirmidhi transmitted it.

Anas said that God’s messenger used to raise his hands in supplication so that the whiteness under his armpits was visible.

Sahl b. Sa‘d told of the Prophet being accustomed to place his two fingers opposite his shoulders and make supplication.

He will give him as peedy answer, or store it up for him in the next world, or turn away from him an equivalent amount of evil.” Those who heard it said they would then make many supplications and he replied that God was more ready to answer than they were to ask.Ahmad transmitted it.

that of one who is wronged till help comes, that of a pilgrim till he comes home, that of one engaged in jihad till he stops, that of a sick person till he recovers, and that of someone for an absent brother. Then he added, “The one of those which gets the quickest answer is that for an absent brother.” Baihaqi transmitted it in [Kitab] ad-Da'awat al-kabir.

Abu Huraira and Abu Said reported God’s messenger as saying, “People will not sit remembering God without the angels surrounding them, mercy covering them, peace(1) descending on them, and God mentioning them among those who are with Him.” 1. Here I have translated as-sakina as "peace” , but cf. p.448, n. 2.Muslim transmitted it.
