﴿ بِسْمِ ٱللَّهِ ٱلرَّحْمَٰنِ ٱلرَّحِيمِ يَٰٓأَيُّهَا ٱلْمُزَّمِّلُ ﴾

“O THOU enwrapped one!”

And from his narration on the authority of Ibn 'Abbas that he said concerning Allah's saying (O thou wrapped up in your raiment!): '(O thou wrapped up in your raiment!) He is referring here to Muhammad (pbuh) who wrapped himself up in his raiment in order to pray.
