TABARANI 7568:
from Rasūl Allāh Ṣallá —
[Machine] I heard the Messenger of Allah ﷺ say, "Whoever goes to bed in a state of purity and remembers Allah until he falls asleep, he will not be overcome by sleep for an hour of the night without asking Allah for something good in this world and the Hereafter, except that Allah will grant it to him."
الطبراني ٧٥٦٨:
عن رسول الاه صلى —
سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ «مَنْ آوَى إِلَى فِرَاشِهِ طَاهِرًا يَذْكُرُ اللهَ حَتَّى يُدْرِكَهُ النُّعَاسُ لَمْ يَتَغَلَّبْ سَاعَةً مِنَ اللَّيْلِ يَسْأَلُ اللهَ شَيْئًا مِنْ خَيْرِ الدُّنْيَا وَالْآخِرَةِ إِلَّا أَعْطَاهُ اللهُ إِيَّاهُ»
