Which sins are kabeerah (major) and sagheerah (minor)?

Answer

All sins are kabaa-ir (major) literally speaking. Hadhrat Aishah

(radhiyallahu anha) said: "Beware of minimizing sin." There is no 'minor' sin. Whoever believes sin to be 'sagheerah' (minor) believes that Allah Ta'ala is insignificant – Nauthubillaah! The classification of sins into major and minor is of technical significance only. Theft is 'minor' in relation to murder. Verbal abuse is 'minor' in relation to physical assault. Besides the technical discussion and meaning of these terms, one should fear and abhor every sin and regard it to be major. There is the danger of the elimination of Imaan if a person commits a sin with the notion that it is 'small', 'minor' or insignificant.
