SHAFAQNA – It is narrated from Imam Sadeq (AS) who narrated from his father who narrated from the Prophet of Islam (PBUH) who said: Whoever repents (to Allah (SWT)) and does good deeds in the remaining of his/her life, will not be interrogated for his/her past sins. And whoever commits sins and does bad deeds in the remaining of his/her life, will be interrogated for all his/her deeds throughout his/her life [1]. This narration (Hadith) reminds us that we must start appropriate behaviour (based on religion) immediately, as we do not know how long we will live in this world. This is the reality of life, and has nothing to do with being old or young, as no one is aware how long he/she will live.
