9. A number of our people have narrated from Ahmad ibn abu ‘Abd Allah from Ahmad ibn Musa from Ali ibn Ja’far from Muhammad ibn Muslim who has said the following: “Abu ‘Abd Allah , has said that the Messenger of Allah, O Allah, grant compensation to Muhammad and his family worthy of their services to Your cause, has said this. ‘You should touch the corner (of the Black Stone); it is the right hand of Allah among His creatures with which He shakes hands with His creatures, like shaking hands by a slave - or a man (uncertainty is by the narrator) - and those who touch it bear witness to their standing up to their covenant.’”
