عَنْ جَابِرٍ رَضِيَ اللَّهُ عَنْهُ قَالَ كَانَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ لَا يَنَامُ حَتَّى يَقْرَأَ الم تَنْزِيلُ السَّجْدَةَ وَتَبَارَكَ الَّذِي بِيَدِهِ الْمُلْكُ
It is narrated from Sayyiduna Jabir (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) would not go to sleep without reciting Surah As-Sajdah and Surah Al-Mulk.
