15. A number of our people have narrated from Ahmad ibn Muhammad from Fadhal from Abu Jamila from Muhammad al-Halabi from Abu ‘Abdallah عليه السلام who has said the following: “The Messenger of Allah has said, ‘Allah presented my ’Ummah (followers) to me in the realm of clay and taught me their names just as He had taught all the names to Adam. The (groups of) people of flags passed by and I prayed to ask forgiveness for Ali عليه السلام and his followers. My Lord has promised me a quality for the Shi‘a of Ali عليه السلام .’ It was asked, ‘What is that quality Oh Messenger of Allah?’ He replied, ‘It is forgiveness for those of them who have faith and that no minor or major sins from them will be left without being changed to good deeds.’
