Allah SWT says:
Verily! man is in loss,
except those who believe, and do good deeds, and recommend one another to the truth,
and recommend one another to the patience. Al- Asr 103: 1-3
In this Surah Muslims have been given very great guidence; Which is this, that just as it is necessary to correct ones's own Iman and Actions, so also it is equally important to struggle for the improvement of the Iman and actions of other Muslims. In particular one's immediate family and relatives. Correcting one's own personal Iman and actions is not enough. For this reason in the light of Quran and Hadith it is obligatory (Fard) to order to good and forbid evil to the extent of one's capacity. In this matter not only the ordinary Muslim but many religious Muslims are negligent and think that one's personal actions are sufficient; being totally in different to what their children and family do.
May Allah give all of us the strength to act on the guidence given in this Surah. Amiin.
