Blackening Of The Heart The Prophet (sal Allahu alaihi wa sallam) said: “A person regularly tells lies and adopts falsehood (as his policy), till a black point is imprinted on his heart, and slowly and slowly the whole heart becomes black. At that time his name is entered in the list of liars before Allah.” [Imaam Maalik] Each lie, each untruth, each dishonesty, marks our heart with a black dot. That person becomes doomed whose entire heart gets blackened. The only way to wash away the dots already there, is to sincerely repent of our misdeeds. Repentance includes an honest vow to oneself and Allah (subhana wa ta’ala) not to repeat those bad deeds.
