Make tawba not just for sins you've committed, but also for obligations you haven't fulfilled.

Imprisoned is he whose heart is imprisoned from Allâh. Captured is he who is captured by his desires.

Avoiding the temptation to sin and being patient upon that, is greater than being patient whilst being afflicted with trials.

Beautiful leaving (hajr), is to leave without harming, beautiful pardoning is to pardon without rebuking, and beautiful patience is to be patient without complaining.

Sins cause harm and repentance removes the cause
