NASAI-KUBRA 10569:
from Farwah b. Nawfal from his father —
[Machine] "That the Messenger of Allah ﷺ said, 'So what have you come with?' I said, 'I have come, O Messenger of Allah, to learn something that I can say during my sleep.' He said, 'When you lie down on your bed, recite Surah Al-Kafirun (Chapter 109) until the end, for it is a protection from shirk (associating partners with Allah).'"
الكبرى للنسائي ١٠٥٦٩:
عن فروه بن نوفل عن أبيه —
أَنَّ رَسُولَ اللهِ ﷺ قَالَ «فَمَجِيءُ مَا جَاءَ بِكَ؟» قَالَ قُلْتُ جِئْتُ يَا رَسُولَ اللهِ لِتُعَلِّمَنِي شَيْئًا أَقَوْلُهُ عِنْدَ مَنَامِي قَالَ إِذَا أَخَذَتْ مَضْجَعَكَ فَاقْرَأْ {قُلْ يَا أَيُّهَا الْكَافِرُونَ} [الكافرون 1] ثُمَّ نَمْ عَلَى خَاتِمَتِهَا فَإِنَّهَا بَرَاءَةٌ مِنَ الشِّرْكِ
