SHAFAQNA – It is narrated from the Prophet of Islam (PBUH) who said: If someone’s brother offers him an apology and he does not accept it, his sin is the same as a blackmailer . In another narration, The Prophet (PBUH) said: If a person’s brother comes to him to offer an apology, must accept it whether that apology is justified or unjustified; and if the apology is not accepted, that person will not join me near the Pond (of Kawthar) .
The prophet (PBUH) advised Imam Ali (AS) by saying: Anyone who does not accept an apology whether the person offering it, is telling the truth or not, will not have my intercession . It is also narrated from Imam Ali (AS) who said: Not accepting an apology is a great sin . Imam Sajjad (AS) in one of his prayers in Alsahifah Alsajjadiyyah said: O’ Allah (SWT), I apologise to you if in my presence, someone was oppressed and I could not help him; and someone who committed a bad deed to me and I did not accept his apology .
