ʿUmar asked the people regarding Allah's Statement: 'When comes the Help of Allah (to you O Muhammad against your enemies) and the conquest of Mecca.' (110.1) They replied, "It indicates the future conquest of towns and palaces (by Muslims)." ʿUmar said, "What do you say about it, O Ibn ʿAbbas?" I replied, "(This Surat) indicates the termination of the life of Muhammad. Through it he was informed of the nearness of his death."
عَنْ قَوْلِهِ تَعَالَى {إِذَا جَاءَ نَصْرُ اللَّهِ وَالْفَتْحُ} قَالُوا فَتْحُ الْمَدَائِنِ وَالْقُصُورِ قَالَ مَا تَقُولُ يَا ابْنَ عَبَّاسٍ قَالَ أَجَلٌ أَوْ مَثَلٌ ضُرِبَ لِمُحَمَّدٍ ﷺ نُعِيَتْ لَهُ نَفْسُهُ
