وَعَنْ جَابِرٌ
أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ كَانَ لَا يَنَامُ حَتَّى يَقْرَأَ: (آلم تَنْزِيل) و (تَبَارَكَ الَّذِي بِيَدِهِ الْمُلْكُ)
Jabir said it was the Prophet’s custom not to go to sleep till he had recited “A. L. M The sending down,” (Qur’an, 32) and “Blessed is He in whose hand is the kingdom.” Ahmad, Tirmidhi and Darimi transmitted it, Tirmidhi saying this is a sahih tradition. The same is said in Sharh as-sunna, but in al-Masabih it is called gharib.
