The Virtues of Surat As-Saffat

An-Nasa'i recorded that `Abdullah bin `Umar, may Allah be pleased with him, said, "The Messenger of Allah ﷺ used to command us to make our prayers short and he used to recite As-Saffat when he lead us in prayer." This was recorded by An-Nasa'i only.

بِسْمِ اللَّهِ الرَّحْمَـنِ الرَّحِيمِ

Why has the statement been sworn by the angels?

The reason why angels have been sworn by in the Surah particularly - as already submitted - lies in the central theme of this Surah. It aims at refuting the peculiar kind of shirk (ascribing of partners in the pure divinity of Allah) based on which the people of Makkah used to call angels the daughters of Allah. Accordingly, at the very beginning of the Surah, by swearing in the name of the angels, described there were their unique attributes that demonstrated their perfect servitude. In other words, the sense is that should you ponder over these angelic attributes of servitude, they will themselves become a witness before you that their relationship with Allah Ta’ ala is not that of a father and daughter, instead, it is that of servants and the Master.
