1354. hadíth
وَ رَوَى عَبْدُ اَللَّهِ بْنُ سِنَانٍ عَنْ أَبِي عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ قَالَ لَهُ: «اِقْرَأْ «قُلْ هُوَ اَللّٰهُ أَحَدٌ» وَ «قُلْ يٰا أَيُّهَا اَلْكٰافِرُونَ» عِنْدَ مَنَامِكَ فَإِنَّهَا بَرَاءَةٌ مِنَ اَلشِّرْكِ وَ «قُلْ هُوَ اَللّٰهُ أَحَدٌ» نِسْبَةُ اَلرَّبِّ عَزَّ وَ جَلَّ.
Abdullah ibn Sinan reports from Imam Jafar ibn Muhammad Al-Sadiq (a.s) who said: "Recite 'Qul Huwa Allahu Ahad' (Surah Al-Ikhlas) and ‘Qul ya-ayyuhal kaafirun’ (Surah al-Kafirun) before you sleep, for they are a declaration of freedom from shirk (associating partners with Allah (swt)), and 'Qul Huwa Allahu Ahad' (Surah Al-Ikhlas) affirms the nature of the Lord (azj), Mighty and Majestic."
