There are 182 ayaat in this surah and it was revealed in Makkah.
The reward for reciting this surah is ten times the total number of Jinn and Shayateen that exist.
The reciter of this surah is protected from Shaitan and is safe from falling into disbelief and Shirk. His angels who record his deeds will testify for him on the Day of Judgement that he was from among those who believed in the Prophets of Allah (s.w.t.).
It is narrated from Imam Ja’far as-Sadiq (a.s.) that reciting surah as-Saffaat on every Friday keeps one safe from all types of calamities. His sustenance will increase and his life, wealth and children will be protected from the evil designs of Shaitan and the tyrant rulers of the time.
If one dies soon after reciting this surah, Insha-Allah, he will die the death of a martyr; he will be raised on the Day of Judgement together with the martyrs and will enter Jannah with them.
