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.
