Narrated Ibn 'Abbas:

The Prophet ﷺ said, "O Gabriel, what prevents you. from visiting us more often than you do?" Then this Verse was revealed:--'And we angels descend not but by Command of your Lord. To Him belongs what is before us and what is behind us..' (19.64) So this was the answer to Muhammad.

حَدَّثَنَا خَلاَّدُ بْنُ يَحْيَى، حَدَّثَنَا عُمَرُ بْنُ ذَرٍّ، سَمِعْتُ أَبِي يُحَدِّثُ، عَنْ سَعِيدِ بْنِ جُبَيْرٍ، عَنِ ابْنِ عَبَّاسٍ ـ رضى الله عنهما ـ أَنَّ النَّبِيَّ ﷺ قَالَ " يَا جِبْرِيلُ مَا يَمْنَعُكَ أَنْ تَزُورَنَا أَكْثَرَ مِمَّا تَزُورُنَا ". فَنَزَلَتْ {وَمَا نَتَنَزَّلُ إِلاَّ بِأَمْرِ رَبِّكَ لَهُ مَا بَيْنَ أَيْدِينَا وَمَا خَلْفَنَا} إِلَى آخِرِ الآيَةِ. قَالَ هَذَا كَانَ الْجَوَابَ لِمُحَمَّدٍ ﷺ.
