NASAI-KUBRA 10587:
from Man —
[Machine] After every obligatory prayer, there are ten praises, ten glorifications, and ten declarations of the greatness of Allah. And when he (the person) intends to sleep, he should recite thirty-three glorifications, thirty-three praises, and thirty-four declarations of the greatness of Allah, and if he persistently does this, he will enter paradise.
الكبرى للنسائي ١٠٥٨٧:
عن من —
فِي دُبُرِ كُلِّ صَلَاةٍ مَكْتُوبَةٍ عَشْرَ تَحْمِيدَاتٍ وَعَشْرَ تَسْبِيحَاتٍ وَعَشْرَ تَكْبِيرَاتٍ وَإِذَا أَرَادَ أَنْ يَنَامَ ثَلَاثًا وَثَلَاثِينَ تَسْبِيحَةً وَثَلَاثًا وَثَلَاثِينَ تَحْمِيدَةً وَأَرْبَعًا وَثَلَاثِينَ تَكْبِيرَةً وَدَاوَمَ عَلَيْهِنَّ دَخَلَ الْجَنَّةَ»
