(131) And indeed Iblis (Satan) did prove true his thought about them: and they followed him, all except a group of true believers (in the Oneness of Allah).

(132) And those who strive against Our Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.), to frustrate them, they will be brought to the torment.

(133) And surely, all - everyone of them will be brought before Us.

(134) It will be but a single Saihah (shout), so behold they will all be brought up before Us!

(135) They cannot help them, but they will be brought forward as a troop against those who worshipped them (at the time of Reckoning).

(140) [Dawud (David)] said (immediately without listening to the opponent): "He has wronged you in demanding your ewe in addition to his ewes. And, verily, many partners oppress one another, except those who believe and do righteous good deeds, and they are few." And Dawud (David) guessed that We have tried him and he sought Forgiveness of his Lord, and he fell down prostrate and turned (to Allah) in repentance.
