Surah 6. Al-An'am, Ayah 39

See note [4] on 14:4 .

The limited free will of man makes a little difference. If he sees the Signs but shuts his ears to the true Message, and refuses (like a dumb thing) to speak out the Message which all Nature proclaims, then according to the Plan ( of his limited free-will) he must suffer and wander, just as, in the opposite case, he will receive grace and salvation.
