SHAFAQNA – Violating the rights of others will change the divine blessings and gifts (either the blessings will reduce, stop or will change into completely the opposite). Murder will bring regret. Oppression and cruelty will bring difficulties, hardships and worries. Drinking wine and alcohol will cause disgrace. Adultery will prevent divine sustenance. Cutting relation with relatives will hasten the death. The sin which prevents the prayers to be accepted by Allah (SWT) and will make life dull and dark is, disobeying father and mother .
