Surat Maryam (63-64)

{تِلْكَ الْجَنَّةُ الَّتِي نُورِثُ مِنْ عِبَادِنَا مَن كَانَ تَقِيّاً} (مريم: 63)

63- That high garden which we give to the pious people of Our Servants who preferred the obedience of their Lord and observed patience for it, and were not tempted by the temptations of the world.

{وَمَا نَتَنَزَّلُ إِلَّا بِأَمْرِ رَبِّكَ لَهُ مَا بَيْنَ أَيْدِينَا وَمَا خَلْفَنَا وَمَا بَيْنَ ذَلِكَ وَمَا كَانَ رَبُّكَ نَسِيّاً} (مريم: 64)

64- Gabriel (peace be upon him) said: We do not come down to earth but by the command of Allah, for He owns the affairs of the world and the Hereafter and that is between them, and Allah will not abandon His Prophets.

It was reported in Sahih Al Bukhari and others that the Messenger of Allah (peace be upon him) said to Gabriel: What does prevent you from visiting us more? Then the Ayah was revealed.
