The Messenger of Allah ﷺ while reciting the Qur'an recited its surah containing sajda, and he performed prostration and we also prostrated along with him (but we were so overcrowded) that some of us could not find a place for our forehead (when prostrating ourselves).  

أَنَّ النَّبِيَّ ﷺ كَانَ يَقْرَأُ الْقُرْآنَ فَيَقْرَأُ سُورَةً فِيهَا سَجْدَةٌ فَيَسْجُدُ وَنَسْجُدُ مَعَهُ حَتَّى مَا يَجِدُ بَعْضُنَا مَوْضِعًا لِمَكَانِ جَبْهَتِهِ  

Sometimes the Messenger of Allah ﷺ recited the Qur'an, and would pass by (recite) the verse of sajda and performed prostration and he did this along with us, but we were so crowded in his company that none of us could find a place for performing prostration. (and it was done on occasions) other than prayer.  

رُبَّمَا قَرَأَ رَسُولُ اللَّهِ ﷺ الْقُرْآنَ فَيَمُرُّ بِالسَّجْدَةِ فَيَسْجُدُ بِنَا حَتَّى ازْدَحَمْنَا عِنْدَهُ حَتَّى مَا يَجِدُ أَحَدُنَا مَكَانًا لِيَسْجُدَ فِيهِ فِي غَيْرِ صَلاَةٍ  

The Apostle of Allah ﷺ recited (Surat) al Najm and performed prostration during its recital and all those who were along with him also prostrated themselves except one old man who took a handful of pebbles or dust in his palm and lifted it to his forehead and said: This is sufficient for me. 'Abdullah said: I saw that he was later killed in a state of unbelief.  

عَنِ النَّبِيِّ ﷺ أَنَّهُ قَرَأَ { وَالنَّجْمِ} فَسَجَدَ فِيهَا وَسَجَدَ مَنْ كَانَ مَعَهُ غَيْرَ أَنَّ شَيْخًا أَخَذَ كَفًّا مِنْ حَصًى أَوْ تُرَابٍ فَرَفَعَهُ إِلَى جَبْهَتِهِ وَقَالَ يَكْفِينِي هَذَا قَالَ عَبْدُ اللَّهِ لَقَدْ رَأَيْتُهُ بَعْدُ قُتِلَ كَافِرًا  

There should be no recital along with the Imam in anything, and alleged that he recited:" By the star when it sets" (Surah Najm) before the Messenger of Allah ﷺ and he did not prostrate himself.  

لاَ قِرَاءَةَ مَعَ الإِمَامِ فِي شَىْءٍ وَزَعَمَ أَنَّهُ قَرَأَ عَلَى رَسُولِ اللَّهِ ﷺ { وَالنَّجْمِ إِذَا هَوَى} فَلَمْ يَسْجُدْ  

Abu Huraira recited before them:" hen the heaven burst asunder" (al-Qur'an, lxxxiv. 1) and performed prostration. After completing (the prayer) he informed them that the Messenger of Allah ﷺ has prostrated himself at it (this verse).  

أَنَّ أَبَا هُرَيْرَةَ قَرَأَ لَهُمْ { إِذَا السَّمَاءُ انْشَقَّتْ} فَسَجَدَ فِيهَا فَلَمَّا انْصَرَفَ أَخْبَرَهُمْ أَنَّ رَسُولَ اللَّهِ ﷺ سَجَدَ فِيهَا  

A hadith like this has been narrated by AbuSalama on the authority of Abu Huraira.  

عَنِ النَّبِيِّ ﷺ بِمِثْلِهِ  

We performed prostration along with the Messenger of Allah ﷺ (as he recited these verses: )" When the heaven burst asunder" and" Read in the name of Thy Lord" (al-Qur'an, xcvi. 1).  

سَجَدْنَا مَعَ النَّبِيِّ ﷺ فِي { إِذَا السَّمَاءُ انْشَقَّتْ} وَ { اقْرَأْ بِاسْمِ رَبِّكَ}  

The Messenger of Allah ﷺ prostrated himself (while reciting these verses)." When the heaven burst asunder" ;" Read in the name of Thy Lord".  

عَنْ عَبْدِ الرَّحْمَنِ الأَعْرَجِ مَوْلَى بَنِي مَخْزُومٍ عَنْ أَبِي هُرَيْرَةَ أَنَّهُ قَالَ سَجَدَ رَسُولُ اللَّهِ ﷺ فِي { إِذَا السَّمَاءُ انْشَقَّتْ} وَ { اقْرَأْ بِاسْمِ رَبِّكَ}  

A hadith like this has been transmitted by Abual-Rahman al-Araj on the authority of Abu Huraira.  

عَنْ رَسُولِ اللَّهِ ﷺ مِثْلَهُ  

I said the night prayer along with Abu Huraira and -as he recited:" When the heaven burst asunder," he performed prostration. Isaid to him: What prostration is this? He said: I prostrated myself (on this occasion of recital) behind Abu'I-Qasim (Muhammad. may peace be upon him), and Iwould go on doing this till I meet him (in the next world). Ibn 'Abu al-A'la said: (Abu Huraira uttered this: ) I would not abandon performing prostration.  

صَلَّيْتُ مَعَ أَبِي هُرَيْرَةَ صَلاَةَ الْعَتَمَةِ فَقَرَأَ { إِذَا السَّمَاءُ انْشَقَّتْ} فَسَجَدَ فِيهَا فَقُلْتُ لَهُ مَا هَذِهِ السَّجْدَةُ فَقَالَ سَجَدْتُ بِهَا خَلْفَ أَبِي الْقَاسِمِ ﷺ فَلاَ أَزَالُ أَسْجُدُ بِهَا حَتَّى أَلْقَاهُ وَقَالَ ابْنُ عَبْدِ الأَعْلَى فَلاَ أَزَالُ أَسْجُدُهَا  

" Behind Abu'l-Qasim" ﷺ.  

عَنِ التَّيْمِيِّ بِهَذَا الإِسْنَادِ غَيْرَ أَنَّهُمْ لَمْ يَقُولُوا خَلْفَ أَبِي الْقَاسِمِ ﷺ  

I saw Abu Huraira performing prostration (while reciting this verse: )" When the heaven burst asunder." I said to him: Do you prostrate yourself (while reciting) i? He said: Yes, I saw my best Friend ﷺ prostrating himself on (the recital of this verse) and I shall continue prostrating till I meet him. Shu'ba asked: Do you mean (by Friend) the Messenger of Allah ﷺ? He said: Yes.  

رَأَيْتُ أَبَا هُرَيْرَةَ يَسْجُدُ فِي { إِذَا السَّمَاءُ انْشَقَّتْ} فَقُلْتُ تَسْجُدُ فِيهَا فَقَالَ نَعَمْ رَأَيْتُ خَلِيلِي ﷺ يَسْجُدُ فِيهَا فَلاَ أَزَالُ أَسْجُدُ فِيهَا حَتَّى أَلْقَاهُ قَالَ شُعْبَةُ قُلْتُ النَّبِيَّ ﷺ قَالَ نَعَمْ
