SHAFAQNA – It is narrated from the Prophet of Islam (PBUH) who said: There are three sins which attract (Divine) punishment in this world and will not be delayed until the hereafter: Unkind behaviour towards parents, oppressing and coercing other people, and ingratitude towards others good deeds . In another narration, the Prophet (PBUH) said: Two things are punished in this world by God: Ingratitude and being disowned by the parents .
