Silsilat al-Ahadith al-Sahihah

Sayyiduna Mu’adh (may Allah be pleased with him) says: I said, “O Messenger of Allah! Advise me.” He (peace and blessings be upon him) said: “Worship Allah as if you see Him, consider yourself among the dead, remember Allah at every stone and tree, and whenever you commit an evil deed, follow it up immediately with a good deed (so that the effect of the evil is erased); for a hidden evil, do a hidden good deed, and for an open evil, do an open good deed.”
