91:1 (I swear) by the sun and its brightness,

91:2 and the moon that trails (and reflects) sun's light.

91:3 And by the day as it shows up (the sun’s) brightness.

91:4 And by the night, which draws a veil over it.

91:5 And by the sky, and (by) Him Who made it.

91:6 And by the earth and Him who spread it.

91:7 And by the  'self' (نفس) and the completeness given to it.

91:8 (The human ) was given awareness of its (inner-self's) evil and its virtue.

91:9 He succeeded who purified it,

91:10 and he failed who corrupted it.

91:11 (The people of) Thamûd rejected (the truth) out of arrogance,

91:12 when the most wicked person among them went out (to kill the she-camel).

91:13 The Apostle of Allah ( Saleh  عليه السلام) said to them, 'That is the she-camel of Allah! (Don’t harm it and don’t stop it from) its drink.'

91:14 They denied him and killed the she-camel.   So their Lord destroyed them because of their sin, and leveled them to the ground.

91:15 Allah is stern in punishing the wicked.
