Ruling 1870

The obligation to enjoin good and forbid evil on every mukallaf is greater with respect to his family and relatives. Therefore, if with regard to his family and relatives he feels that they are inattentive to, and unconcerned about, religious obligations such as performing prayers (ṣalāh), keeping fasts (ṣawm), paying the one-fifth tax (khums), and suchlike, or if he sees that they are careless and fearless with regard to committing unlawful acts such as backbiting and lying, then he must prevent improper actions being performed by them and invite them to do good deeds with a greater sense of importance while observing the three levels of enjoining good and forbidding evil.

However, with regard to one’s mother and father, the obligatory precaution is that he must guide them by adopting a soft and gentle approach, and he must never be harsh with them.
