Sunan an-Nasa'i, Volume 2, Book 12, Hadith 1046 (DarusSalam) ⓘ

It was narrated that Ibn 'Abbas said: "The Prophet drew back the curtain when the people were in rows behind Abu Bakr, may Allah be pleased with him, and said: 'O people, there is nothing left of the features of Prophethood except a good dream that a Muslim sees or is seen by others for him.' Then he said: 'Verily, I have been forbidden from reciting the Qur'an when bowing or prostrating. As for bowing, glorify the Lord therein, and as for prostration, strive hard in supplication for it is more deserving of a response.'"

أَخْبَرَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، قَالَ حَدَّثَنَا سُفْيَانُ، عَنْ سُلَيْمَانَ بْنِ سُحَيْمٍ، عَنْ إِبْرَاهِيمَ بْنِ عَبْدِ اللَّهِ بْنِ مَعْبَدِ بْنِ عَبَّاسٍ، عَنْ أَبِيهِ، عَنِ ابْنِ عَبَّاسٍ، قَالَ كَشَفَ النَّبِيُّ صلى الله عليه وسلم السِّتَارَةَ وَالنَّاسُ صُفُوفٌ خَلْفَ أَبِي بَكْرٍ - رضى الله عنه - فَقَالَ ‏ "‏ أَيُّهَا النَّاسُ إِنَّهُ لَمْ يَبْقَ مِنْ مُبَشِّرَاتِ النُّبُوَّةِ إِلاَّ الرُّؤْيَا الصَّالِحَةُ يَرَاهَا الْمُسْلِمُ أَوْ تُرَى لَهُ - ثُمَّ قَالَ - أَلاَ إِنِّي نُهِيتُ أَنْ أَقْرَأَ رَاكِعًا أَوْ سَاجِدًا فَأَمَّا الرُّكُوعُ فَعَظِّمُوا فِيهِ الرَّبَّ وَأَمَّا السُّجُودُ فَاجْتَهِدُوا فِي الدُّعَاءِ قَمِنٌ أَنْ يُسْتَجَابَ لَكُمْ ‏" ‏ ‏.‏
