"There is no Believer who does not make an error sometimes, or who does not make some mistake which they persist in and do not abandon until they leave this world. For, in truth, the Believer was created to be frequently tried and tested: someone who often regrets (then) forgets, again. But when corrected, they correct themselves."
Reported by at-Tabarani in al-Mujamul Kabir (no. 11,810); hasan."
