He said: Abu Nasr Muhammad b. al-Husain reported to me from Abu Ali Ahmad b. Muhammad al-Sawli, who reported from Abdul Aziz b. Yahya al-Jaloodi, who reported from al-Husain b. Hameed, who reported from Mukhawwal b. Ibrahim, who reported from Swaleh b. Abul Aswad, who reported from Mahfooz b. Ubaidullah, from a Sheikh from Hadhramaut, from Muhammad b. al-Hanafiyyah - may ALLAH (SWT) bless him with mercy, who said:
Once, while AMIRUL MO'MINEEN ALI B.ABI TALIB (ASWS), peace be upon him, was going around the Ka'bah , he came across a man who had clung to the curtains of the sacred house, saying: 'O, He, Whom one hearing does not distract from another and O, He, Who is not misled by the seekers, and O, He, Who is not wearied by the insistent supplication. Grant me the coolness of Your Pardon and the sweetness of Your mercy."
AMIRUL MO'MINEEN (A.S.) asked him: "Is this your prayer?" The man said: "So, you heard it?" He said: "Yes". The man said: "Pray this way at the end of every Daily prayer. By ALLAH (SWT), when a faithful prays with these words at the end of the Daily prayer, ALLAH (SWT) forgives him all his sins even if they equal the heavenly stars in number, or the pebbles and the earth in abundance.
" Then AMIRUL MO'MINEEN (ASWS) , told him: "I have the knowledge of it, and ALLAH (SWT) is Infinite, Beneficent." The man who was al-Khidhr, peace be upon him, said: "By ALLAH (SWT), you are right O, AMIRUL MO'MINEEN (ASWS) . Over everyone endowed with knowledge, there is One Who knows most." And may ALLAH (SWT) bless our master Muhammad, the PROPHET (SAWW) and his pure progeny.
