What did Ibn `Abbas interpret the Verse 'When come the Help of Allah and the conquest (of Mecca)(110.1)' to portend according to Prophet Muhammad (peace be upon him)?
 Narrated Sa`id bin Jubair:                     About Ibn `Abbas: `Umar bin Al-Khattab used to treat Ibn `Abbas very favorably `Abdur Rahman bin `Auf said to him. "We also have sons that are equal to him (but you are partial to him.)" `Umar said, "It is because of his knowledge." Then `Umar asked Ibn `Abbas about the interpretation of the Verse:- 'When come the Help of Allah and the conquest (of Mecca) (110.1) Ibn `Abbas said. "It portended the death of Allah's Apostle, which Allah had informed him of." `Umar said, "I do not know from this Verse but what you know."
