7. Prayer (Kitab Al-Salat) Prostration while reciting the Qur'an - كتاب سجود القرآن
3) Chapter: A View That There Is Prostration In Mufassal Surahs
Narrated 'Abd Allah (b. Mas'ud):
The Messenger of Allah (ﷺ) recited Surah al-Najm and prostrated himself. No one remained there who did not prostrate (along with him). A man from the people took a handful of pebbles or dust and raised it to his face saying: This is enough for me. 'Abd Allah (b. Mas'ud) said: I later saw him killed as an infidel.
3) باب مَنْ رَأَى فِيهَا السُّجُودَ
حَدَّثَنَا حَفْصُ بْنُ عُمَرَ، حَدَّثَنَا شُعْبَةُ، عَنْ أَبِي إِسْحَاقَ، عَنِ الأَسْوَدِ، عَنْ عَبْدِ اللَّهِ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَرَأَ سُورَةَ النَّجْمِ فَسَجَدَ فِيهَا وَمَا بَقِيَ أَحَدٌ مِنَ الْقَوْمِ إِلاَّ سَجَدَ فَأَخَذَ رَجُلٌ مِنَ الْقَوْمِ كَفًّا مِنْ حَصًى أَوْ تُرَابٍ فَرَفَعَهُ إِلَى وَجْهِهِ وَقَالَ يَكْفِينِي هَذَا . قَالَ عَبْدُ اللَّهِ فَلَقَدْ رَأَيْتُهُ بَعْدَ ذَلِكَ قُتِلَ كَافِرًا .
حكم: صحيح (الألباني)
