لَا تَقْنَطُوا مِنْ رَحْمَةِ اللَّهِ
Do not despair of Allah's mercy. (al-Zumar 39:53)
Other verses and reports are cited in support of the breadth of divine mercy. Their significance is that a servant must not despair and that pardon of sins should not be treated as inherently inconceivable.
General encouragement must not be read as cancelling repentance, the distinction between faith and shirk, or the warning passages. Fear and hope belong together: seriousness about disobedience and confidence that mercy remains possible.
