SHAFAQNA –
It is narrated from Imam Hussain (AS) who said: Avoid whatever makes you to apologise because a believer is not a wrong doer, hence does not need to apologise; but a hypocrite commits bad deeds every day and then apologises [1]. According to Imam Hussain (AS) a believer must manage his/her behaviour at all the times in order to stay clear of sins, wrong doing and making obvious mistakes and in that case he/she will not need to make apologies.
