SHAFAQNA – The Prophet of Islam (PBUH) said: How good it is when someone on the Day of Judgment has in his/her record under each sin this sentence written: “I ask God to forgive me” . In another narration, the Prophet Said: Beware that, there are sins in you and your cure is repenting . It is also narrated from the Prophet (PBUH) who said: Iblis said: I swear to Your majesty that until Your servants have life in their bodies, I will not stop from leading them astray.
God replied: Swear to My majesty and glory, until the time that they ask Me for forgiveness, I will forgive them . In this regard, it is narrated from Imam Sadeq (AS) who said: When a believing servant commits a sin, God will give him/her a 7 hours respite, if he/she asks for forgiveness from God, nothing will be written and if that period is passed and has not repented, one sin will be registered.
Sometimes a believer remembers his/her sin after 20 years and asks for forgiveness from God and the Supreme Being forgives him/her but a disbeliever forgets about his/her sin at the time of committing it . It is also narrated from Imam Reza (AS) who said: The one who commits a sin and then do it again, is like someone who is making fun of his/her God .
