Every sin is a wound you inflict on yourself. Allah is not diminished by it. Your enemy is not damaged by it. Only your own soul takes the hit. Re-think the next 'small' sin.

There is a discipline the Salaf practiced called muḥāsabah, accounting. At the end of each day, they would sit and count: what good did I do today, what sin did I commit, what was its destination? They understood that every act lands somewhere. If the act is good, it lands as light in the soul; if the act is sin, it lands as a black point. The Prophet ﷺ described this in a hadith: when the believer sins, a black point is placed on his heart; if he repents, it is wiped off; if he continues, the black points spread until the heart is covered (Tirmidhī, ḥasan). This is verse 111 made tangible. The sin DOES go somewhere; it goes on YOUR heart. Now look at your heart in honesty. How many black points have you let accumulate without tawbah? The mercy is that the wiping is still available. Tawbah erases the points. Without tawbah, the points become a covering, and a covered heart cannot receive light. So tonight, before sleep, sit for two minutes. Ask the day for its black points. Tawbah for each. Sleep with a wiped heart. Yā Allāh, the day every soul earns for or against itself, do not let our earnings be only against us. Erase the black points before they cover us; replace them with the light of Your forgiveness. Āmīn.
