It is reported from Abu Salamah that while leading them in prayer, Abu Hurayrah recited,

﴿إِذَا السَّمَآءُ انشَقَّتْ ﴾

(When the heaven is split asunder.) and he prostrated during its recitation. Then when he completed the prayer, he informed them that the Messenger of Allah prostrated during its recitation. This was recorded by Muslim and An-Nasa'i on the authority of Malik. Al-Bukhari recorded from Abu Rafi` that he prayed the Night prayer with Abu Hurayrah) recited,

﴿إِذَا السَّمَآءُ انشَقَّتْ ﴾

(When the heaven is split asunder.) then he prostrated. So Abu Rafi` said something to him about it (questioning it). Abu Hurayrah replied, "I prostrated behind Abul-Qasim (the Prophet ), and I will never cease prostrating during its recitation until I meet him.''

﴿بِسْمِ اللَّهِ الرَّحْمَـنِ الرَّحِيمِ﴾

In the Name of Allah, the Most Gracious, the Most Merciful.

﴿إِذَا السَّمَآء انشَقَّتْ- وَأَذِنَتْ لِرَبّهَا وَحُقَّتْ- وَإِذَا الاْرْضُ مُدَّتْ- وَأَلْقَتْ مَا فِيهَا وَتَخَلَّتْ- وَأَذِنَتْ لِرَبّهَا وَحُقَّتْ- يأَيُّهَا الإِنسَـنُ إِنَّكَ كَادِحٌ إِلَى رَبّكَ كَدْحاً فَمُلَـقِيهِ- فَأَمَّا مَنْ أُوتِىَ كِتَـبَهُ بِيَمِينِهِ- فَسَوْفَ يُحَاسَبُ حِسَاباً يَسِيراً- وَيَنقَلِبُ إِلَى أَهْلِهِ مَسْرُوراً- وَأَمَّا مَنْ أُوتِىَ كِتَـبَهُ وَرَآء ظَهْرِهِ- فَسَوْفَ يَدْعُو ثُبُوراً- وَيَصْلَى سَعِيراً- إِنَّهُ كَانَ فِى أَهْلِهِ مَسْرُوراً- إِنَّهُ ظَنَّ أَن لَّن يَحُورَ- بَلَى إِنَّ رَبَّهُ كَانَ بِهِ بَصِيراً-﴾

(1. When the heaven is split asunder,) (2. And listens to and obeys its Lord -- and it must do so.) (3. And when the earth is stretched forth,) (4. And has cast out all that was in it and became empty.) (5. And listens to and obeys its Lord -- and it must do so.) (6. O man! Verily, you are returning towards your Lord with your deeds and actions, a sure returning, and you will meet.) (7. Then as for him who will be given his Record in his right hand,) (8. He surely will receive an easy reckoning,) (9. And will return to his family Masrur (in joy)!) (10. But whosoever is given his Record behind his back,) (11. He will invoke destruction,) (12. And he shall enter a blazing Fire, and made to taste its burning.) (13. Verily, he was among his people in joy!) (14. Verily, he thought that he would never return!) (15. Yes! Verily, his Lord has been ever beholding him!)
