Tafsir of Al-Isra 17:13-14

14

"We have fastened the augury of every man to his own neck": therefore one does not need to take omens from a bird. : This is to remove the superstition of the disbelievers who used to take omens from birds etc., as if to say, "The causes and consequences of good fortune or bad fate exist in man's own person. He merits good fortune because of his own good conduct and good judgment, and likewise, suffers the consequences of evil fate by the lack of these". This was necessitated because foolish people always try to attribute their misfortunes to external causes, when in fact our fate depends on our own deeds, good or bad. If they probe into the causes, they will find that their fate was decided by their own good or bad qualities and judgments.
