Sahih Muslim
The Book of Faith (Kitab Al-Iman)
Book Number: 001 / Hadith Number: 306
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.
