He came to the Prophet ﷺ and said: “O Messenger of Allah, teach me something that I may say when I go to my bed.” So he said: “Recite: Say: ‘O you disbelievers’ for verily it is a disavowal of Shirk.” Shuʿbah said: “Sometimes he would say: ‘One time’ and sometime he would not say it.” (Another chain) from Farwah bin Nawfal, from his father: "That he came to the Prophet ﷺ" then he mentioned similar in meaning. And this is more correct. [Abu ʿEisa said:] And Zubair reported this hadith from Ishaq, from Farwah bin Nawfal, from his father from the Prophet ﷺ, with similar wording. This is more appropriate and more correct than the narration of Shuʿbah. The companions of Abu Ishaq were confused in the narration of this hadith. This hadith has been reported through routes other than this. ʿAbdur-Rahman is the brother of Farwah bin Nawfal.  

أَنَّهُ أَتَى النَّبِيَّ ﷺ فَقَالَ يَا رَسُولَ اللَّهِ عَلِّمْنِي شَيْئًا أَقُولُهُ إِذَا أَوَيْتُ إِلَى فِرَاشِي قَالَ اقْرَأْْ ( قلْ يَا أَيُّهَا الْكَافِرُونَ ) فَإِنَّهَا بَرَاءَةٌ مِنَ الشِّرْكِ قَالَ شُعْبَةُ أَحْيَانًا يَقُولُ مَرَّةً وَأَحْيَانًا لاَ يَقُولُهَا حَدَّثَنَا مُوسَى بْنُ حِزَامٍ أَخْبَرَنَا يَحْيَى بْنُ آدَمَ عَنْ إِسْرَائِيلَ عَنْ أَبِي إِسْحَاقَ عَنْ فَرْوَةَ بْنِ نَوْفَلٍ عَنْ أَبِيهِ أَنَّهُ أَتَى النَّبِيَّ ﷺ فَذَكَرَ نَحْوَهُ بِمَعْنَاهُ وَهَذَا أَصَحُّ
