Overall meaning : I swear by the fig and the olive, by Mount Sinai on which Allah spoke to Moses and by the safe and secure city—Makkah—that We have created man in the best form and the finest upright stature and endowed him with pure nature. Then We will reduce him to the lowest of the low in Hell if he disbelieves, except for those who believe and do righteous deeds. These will have a full reward, which will be undiminished and everlasting.
What, then, should make you, man, deny the final judgement of people for their deeds after their death?! Is Allah not the most just of judges to judge among people?!
