(My mother) Umu-l-Fadl heard me reciting "Wal Mursalati ʿUrfan" (77) and said, "O my son! By Allah, your recitation made me remember that it was the last Sura I heard from Messenger of Allah ﷺ. He recited it in the Maghrib prayer. "
أَنَّهُ قَالَ إِنَّ أُمَّ الْفَضْلِ سَمِعَتْهُ وَهُوَ يَقْرَأُ {وَالْمُرْسَلاَتِ عُرْفًا} فَقَالَتْ يَا بُنَىَّ وَاللَّهِ لَقَدْ ذَكَّرْتَنِي بِقِرَاءَتِكَ هَذِهِ السُّورَةَ إِنَّهَا لآخِرُ مَا سَمِعْتُ مِنْ رَسُولِ اللَّهِ ﷺ يَقْرَأُ بِهَا فِي الْمَغْرِبِ
