Hadith on Salat: Glorify Allah in bowing, supplicate in prostration

Ibn Abbas reported: The Messenger of Allah, peace and blessings be upon him, said, “O people, there are no more glad tidings of prophecy except righteous dreams seen by a Muslim, or he is made to see. Verily, I have been prohibited from reciting the Quran while bowing or prostrating in prayer. As for bowing, you should exalt the Lord Almighty. As for prostration, you should exert yourself in supplication, for it is worthy for you to be answered.

عَنْ ابْنِ عَبَّاسٍ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ أَيُّهَا النَّاسُ إِنَّهُ لَمْ يَبْقَ مِنْ مُبَشِّرَاتِ النُّبُوَّةِ إِلَّا الرُّؤْيَا الصَّالِحَةُ يَرَاهَا الْمُسْلِمُ أَوْ تُرَى لَهُ أَلَا وَإِنِّي نُهِيتُ أَنْ أَقْرَأَ الْقُرْآنَ رَاكِعًا أَوْ سَاجِدًا فَأَمَّا الرُّكُوعُ فَعَظِّمُوا فِيهِ الرَّبَّ عَزَّ وَجَلَّ وَأَمَّا السُّجُودُ فَاجْتَهِدُوا فِي الدُّعَاءِ فَقَمِنٌ أَنْ يُسْتَجَابَ لَكُمْ
