Surah Saba Verse 21 - English Translation by Shabbir Ahmed
Surah Sabaوَمَا كَانَ لَهُۥ عَلَيۡهِم مِّن سُلۡطَٰنٍ إِلَّا لِنَعۡلَمَ مَن يُؤۡمِنُ بِٱلۡأٓخِرَةِ مِمَّنۡ هُوَ مِنۡهَا فِي شَكّٖۗ وَرَبُّكَ عَلَىٰ كُلِّ شَيۡءٍ حَفِيظٞ
And yet he (Iblis) had no power at all over them (15:38-41). But We thus distinguish between those who believe in the life to come from those who keep doubting it. And your Lord is Watcher over all things. (Those who deny the Law of Requital easily succumb to their desires)
