Sahl b. Sa’d al-Sa’idi said:
The Messenger of Allahﷺ one day came out to us while we were reciting the Qur’an. He said: Praise be to Allah. The Book of Allah is one, and among you are the red, and among you are the white and among you are the black. Recite it before there appear people who will recite it and straighten it as an arrow is straightened. They will get their reward for it in this world and will not get it in the Hereafter.

حَدَّثَنَا أَحْمَدُ بْنُ صَالِحٍ، حَدَّثَنَا عَبْدُ اللَّهِ بْنُ وَهْبٍ، أَخْبَرَنِي عَمْرٌو، وَابْنُ، لَهِيعَةَ عَنْ بَكْرِ بْنِ سَوَادَةَ، عَنْ وَفَاءِ بْنِ شُرَيْحٍ الصَّدَفِيِّ، عَنْ سَهْلِ بْنِ سَعْدٍ السَّاعِدِيِّ، قَالَ خَرَجَ عَلَيْنَا رَسُولُ اللَّهِ ﷺ يَوْمًا وَنَحْنُ نَقْتَرِئُ فَقَالَ " الْحَمْدُ لِلَّهِ كِتَابُ اللَّهِ وَاحِدٌ وَفِيكُمُ الأَحْمَرُ وَفِيكُمُ الأَبْيَضُ وَفِيكُمُ الأَسْوَدُ اقْرَءُوهُ قَبْلَ أَنْ يَقْرَأَهُ أَقْوَامٌ يُقِيمُونَهُ كَمَا يُقَوَّمُ السَّهْمُ يَتَعَجَّلُ أَجْرَهُ وَلاَ يَتَأَجَّلُهُ " .
