عَنْ عَبْدِ الرَّحْمَنِ بْنِ عَوْفٍ عَنِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ:" ثَلَاثَةٌ تَحْتَ الْعَرْشِ يَوْمَ الْقِيَامَةِ الْقُرْآنُ يُحَاجُّ الْعِبَادَ لَهُ ظَهْرٌ وَبَطْنٌ وَالْأَمَانَةُ وَالرَّحِمُ تُنَادِي: أَلَا مَنْ وَصَلَنِي وَصَلَهُ اللَّهُ وَمَنْ قَطَعَنِي قَطَعَهُ اللَّهُ ". رَوَاهُ فِي شرح السّنة

‘Abdullah b. Khubaib said

We went out one rainy and intensely dark night to look for God’s messenger, and when we caught up on him he said to me, “Say.” I asked him what I was to say, and he replied, “If you recite ‘Say, He is God, One’ and al-Mu'awidhatān (The last 3 sūras of the Qur’ān) three times morning and evening, they will serve you for every purpose.” Tirmidhī, Abū Dāwūd and Nasā’i transmitted it.
