Muwatta Malik 481

حَدَّثَنِي يَحْيَى، عَنْ مَالِكٍ، عَنْ عَبْدِ اللَّهِ بْنِ يَزِيدَ، مَوْلَى الأَسْوَدِ بْنِ سُفْيَانَ عَنْ أَبِي سَلَمَةَ بْنِ عَبْدِ الرَّحْمَنِ، أَنَّ أَبَا هُرَيْرَةَ، قَرَأَ لَهُمْ ‏{‏إِذَا السَّمَاءُ انْشَقَّتْ‏}‏ فَسَجَدَ فِيهَا فَلَمَّا انْصَرَفَ أَخْبَرَهُمْ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم سَجَدَ فِيهَا ‏.‏

Yahya related to me from Malik from Abdullah ibn Yazid, the mawla of al Aswad ibn Sufyan, from Abu Salama ibn Abd ar Rahman that Abu Hurayra recited al-Inshiqaq (Sura 84) to them and prostrated in it. When he had finished he told them that the Messenger of Allah, may Allah bless him and grant him peace, had prostrated in it
