It was narrated from Abu Razeen that

'Umar asked Ibn ‘Abbas (رضي الله عنه) about this verse: “When there comes the Help of Allah (to you, O Muhammad (ﷺ) against your enemies) and the Conquest (of Makkah)" (an-Nasr 105:1). He said: When it was revealed, it was the announcement to the Prophet (ﷺ) of his own death.
