man ʿamila ṣāliḥan fa-li-nafsihī wa-man ʾasāʾa fa-ʿalayhā wa-mā rabbuka bi-ẓallāmin li-l-ʿabīdi
Whoever acts righteously, it is for [the benefit of] his own soul, and whoever does evil, it is to its detriment, and your Lord is not tyrannical to His servants.
— Ali Quli Qarai
Surah Fussilat - Verse 46
46. Whosoever does righteous good deeds, it is for his own self; and whosoever does evil, it is against his own self. And your Lord is not at all unjust to [His] servants.
Favorable and unfavorable consequences follow man’s conducts and he is not supposed to put the blame on others. There is no doubt concerning the fact that whoever does righteous good deeds will reap the benefits. Righteous good deeds are to be based on Qur’anic Injunctions and Islamic teachings. Such person will enjoy Divine Favors. Au contraire, one who commits evil deeds, i.e. turns away from Divine Injunctions and follows concupiscent and satanic desires will pay for the evil consequences thereof. The torments in store for disbelievers are the consequences of their vicious deeds. God Almighty never wrongs His servants and it is worthy of note that any good or evil deed will lead to consequences.
