حَدَّثَنَا مُسَدَّدٌ، حَدَّثَنَا سُفْيَانُ، عَنْ سُلَيْمَانَ بْنِ سُحَيْمٍ، عَنْ إِبْرَاهِيمَ بْنِ عَبْدِ اللَّهِ بْنِ مَعْبَدٍ، عَنْ أَبِيهِ، عَنِ ابْنِ عَبَّاسٍ، أَنَّ النَّبِيَّ صلى الله عليه وسلم كَشَفَ السِّتَارَةَ وَالنَّاسُ صُفُوفٌ خَلْفَ أَبِي بَكْرٍ فَقَالَ ‏"‏يَا أَيُّهَا النَّاسُ إِنَّهُ لَمْ يَبْقَ مِنْ مُبَشِّرَاتِ النُّبُوَّةِ إِلاَّ الرُّؤْيَا الصَّالِحَةُ يَرَاهَا الْمُسْلِمُ أَوْ تُرَى لَهُ وَإِنِّي نُهِيتُ أَنْ أَقْرَأَ رَاكِعًا أَوْ سَاجِدًا فَأَمَّا الرُّكُوعُ فَعَظِّمُوا الرَّبَّ فِيهِ وَأَمَّا السُّجُودُ فَاجْتَهِدُوا فِي الدُّعَاءِ فَقَمِنٌ أَنْ يُسْتَجَابَ لَكُمْ ‏"
Translation
Ibn ‘Abbas said

The Prophet (ﷺ) lifted the curtain while the people were in rows behind Abu Bakr, and said, "O people! Nothing is left of the glad tidings of prophethood except a righteous dream that a Muslim sees or that is seen for him. And indeed, I have been forbidden to recite the Qur'an while bowing or prostrating. As for bowing, glorify the Lord therein, and as for prostration, strive in supplication, for it is proper that you should be answered.">
