And if any one earns sin. he earns it against His own soul: for Allah is full of knowledge and wisdom. An-Nisa 4:111 ⧉
Tafsir:
This world is a place of trial. Everyone may commit mistakes here, both with regard to God as well as to His servants. When someone errs, the right course is that he should sincerely repent and seek the guidance of God, beg for His forgiveness and pray to be assisted to perform only virtuous deeds in future. One who seeks God’s shelter so sincerely, will certainly receive it from Him. By the grace of God, his religious sensibility will be sharpened and he will be enabled to live more prudently in this world. On the other hand, a person may do some wrong, but does not care to admit it; he rather attempts to justify himself. He then gathers his supporters and fights with those who simply intended to inform him of his mistake. Such arrogant, un-repentant individuals and their supporters are the worst criminals in the eyes of God. Their eloquence, used to hide their wrongs, will become meaningless, and the host of supporters, who propped up their arrogance, will be of no avail in the Hereafter.
