Musnad Abu Ya'la al-Mawsili 155:314

'Abdullah ibn 'Umar ibn Aban narrated to us, Husayn ibn 'Ali narrated to us, from Hamzah al-Zayyat, from Abu Ishaq, from al-Agharr Abu Muslim, that he bore witness regarding Abu Hurayrah and Abu Sa'id that they both bore witness regarding the Messenger of Allah (peace and blessings of Allah be upon him) that he said: "When the servant says: 'La ilaha illa Allah wa Allahu Akbar' (There is no god but Allah, and Allah is the Greatest), Allah says: 'My servant has spoken the truth; there is no god but Me, and I am the Greatest.' And when he says: 'La ilaha illa Allah, lahu al-mulk wa lahu al-hamd' (There is no god but Allah, to Him belongs the dominion and to Him belongs the praise), He says: 'My servant has spoken the truth; there is no god but Me, and to Me belongs the dominion and the praise.'" He said: "And when he says: 'La ilaha illa Allah, wa la hawla wa la quwwata illa billah' (There is no god but Allah, and there is no power and no strength except by Allah), He says: 'My servant has spoken the truth; there is no god but Me, and there is no power except by Me.'" Abu Ishaq said: "Then al-Agharr said something I did not understand. So I said to Abu Ja'far: 'What did he say?' He replied: 'Whoever is provided with them at the time of his death, the Fire shall not touch him.'"
