Hadithcore
Sahih Muslim, 161 c
sahih

This hadith, the like of one narrated by Yunus has also been transmitted by Ma'mar on the authority of al-Zuhri who narrated:

Allah the Most Glorious and Exalted revealed this:" You who are shrouded, arise and deliver warning, your Lord magnify, your clothes cleanse and defilement shun," before making the prayer obligatory. I felt terror-stricken as narrated by Uqail.

وَحَدَّثَنِي مُحَمَّدُ بْنُ رَافِعٍ حَدَّثَنَا عَبْدُ الرَّزَّاقِ أَخْبَرَنَا مَعْمَرٌ عَنِ الزُّهْرِيِّ بِهَذَا الإِسْنَادِ نَحْوَ حَدِيثِ يُونُسَ وَقَالَ فَأَنْزَلَ اللَّهُ تَبَارَكَ وَتَعَالَى ‏{‏ يَا أَيُّهَا الْمُدَّثِّرُ‏}‏ إِلَى قَوْلِهِ ‏{‏ وَالرُّجْزَ فَاهْجُرْ‏}‏ قَبْلَ أَنْ تُفْرَضَ الصَّلاَةُ - وَهِيَ الأَوْثَانُ - وَقَالَ ‏

‏ فَجُثِثْتُ مِنْهُ ‏

‏ ‏.‏ كَمَا قَالَ عُقَيْلٌ
