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

Abū Huraira said

The Prophet, on hearing a man reciting “Say, He is God, One” remarked, “It is certain.” I asked him what was certain, and he replied that it was paradise. Mālik, Tirmidhī and Nasā’i transmitted it.
