Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) says regarding the saying of Allah, the Mighty and Majestic: "When the help of Allah and the victory come": "This refers to the conquest of Makkah. In it, the Messenger of Allah (peace and blessings be upon him) was informed of his own death: that he should seek forgiveness from his Lord and know that the time of his death had certainly drawn near."
No one narrated this hadith from Sufyan (may Allah have mercy on him) except Suwayd (may Allah have mercy on him).
