Abu Huraira said that the Prophet used to recite at the dawn prayer on Friday A.L.M. Tanzil1 in the first rak'a, and in the second, “Has there come upon man?"2 1. Al-Qur’an; 32. 2. Al-Qur’an; 76. (Bukhari and Muslim.)

"Allah's Greatest Names is in these two verses: "And your Ilaah (God) is One Ilaah (God), none has the right to be worshipped but He, the Ever-Merciful, the Mercy-Giving' and the beginning of Surah Al 'Imran, "A.L.M Allah, there is no deity but He, the Living, the Eternal."

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.

Abu Sa'id al-Khudri said, “We used to estimate how long God’s Messenger stood at the noon and the afternoon prayer, and we estimated that he stood in the first two rak'as as long as it takes to recite A.L.M. Tanzil, i.e. as-Sajda* (A version has, “In every rak'a as long as it takes to recite thirty verses.” We estimated that he stood half that time in the last two rak'as; that he stood in the first two of the afternoon prayer as long as he did in the last two at noon; and in the last two of the afternoon prayer about half that time.” * Al-Qur'an; 32. This sura has thirty verses. Muslim transmitted it.

“If anyone recites a letter of God’s Book he will be credited with a good deed, and a good deed gets a tenfold reward (Al-Qur’ān, 6:160). I do not say that A.L.M are one letter*, but alif is a letter, lām is a letter and mīm is a letter.” *These letters occur at the beginning of sūras 2, 3, 29, 30, 31 and 32. No satisfactory explanation of their meaning has been given. A brief discussion of them is given by Abdullāh Yūsuf Ali in The Holy Qur’ān, Text, Translation & Commentary (Lahore, 1934 and later editions), note 25. Sea also pp. 118-120. Tirmidhī and Dārimī transmitted it, Tirmidhī saying this is a hasan sahīh tradition whose isnad is gharīb.

Recite the rescuer, which is A.L.M. The sending down (Qur’ān, 32) for I have heard that a man who had committed many sins used to recite it and nothing else. It spread its wing over him and said, “My Lord, forgive him, for he often used to recite me so the Lord most high made it an intercessor for him and said, “Record for him a good deed and raise him a degree in place of every sin.” Khālid said also: It will dispute on behalf of the one who recites it when he is in his grave saying, “O God, if I am a part of Thy Book, make me an intercessor for him; but if I am not a part of Thy Book, blot me out of it.” It will be like a bird putting its wing on him, it will intercede for him and will protect him from the punishment in the grave. He said the same about “Blessed is He.” (Qur’ān, 67) Khālid did not go to sleep at night till he had recited them. Tā’ūs said they were given sixty virtues more than any other sūra in the Qur’ān. Dārimī transmitted it.
