Hadith 1

(The book) ‘Majaalis’ of Al Mufeed – from Muhammad Bin Al Husayn, from Ahmad Bin Muhammad Al Sowly, from Al Jaloudy, from Al Husayn Bin Al Humeyd, from Mukhawwal Bin Ibrahim, from Salih Bin Abu Al Aswad, from Mahfouz Bin Ubeydullah, from Sheykh from the people of Hazramaut, from Muhammad Bin Al Hanafiya, may the Mercy be upon him, said, ‘While Amir Al Momineen-asws was performing Tawaaf of the House (Kaaba) when a man was holding with the curtains (of the Kaaba) and he was saying, ‘O One-azwj Who is not pre-occupied from hearing (one) from hearing (another)! O One-azwj Whom the (number of) beggars do not overwhelm Him-azwj! O One-azwj Whom the persistence of the persistent ones do not Exhaust Him-azwj! Make me taste the coolness of Your-azwj Pardon, and Your-azwj Forgiveness, and sweetness of Your-azwj Mercy! ’
Amir Al Momineen-asws said to him, ‘This is your supplication? ’
The man said to him-asws, ‘And you-asws heard it? ’
He-asws said: ‘Yes’. He said, ‘I supplicate with it and the end of every Salat. By Allah-azwj! No one from the Momineen will supplicate with it in the ends of the Salats, except Allah-azwj will Forgive his sins for him, and even though they may be the number of stars of the sky and its drops, and pebbles of the earth and its soil (grains of sand)’. Amir Al Momineen-asws said to him: ‘The knowledge of that is in my-asws possession, and Allah-azwj is capacious, Benevolent! ’
The man said to him-asws, and he was Al Khizr-as: ‘You-asws speak the truth, by Allah-azwj, O Amir Al Momineen-asws, and above every one with knowledge is a more knowledgeable one [12: 76]’’. [1]
