A 2: There are many proofs from the Qur'an and the Sunnah enjoining doing what is good (Part No. 21; Page No. 170) and righteous to people in general, and to relatives in particular. Allah (Exalted be He) states:
Verily, Allâh enjoins Al-‘Adl (i.e. justice and worshipping none but Allâh Alone - Islâmic Monotheism) and Al-Ihsân [i.e. to be patient in performing your duties to Allâh, totally for Allâh’s sake and in accordance with the Sunnah (legal ways) of the Prophet صلى الله عليه وسلم in a perfect manner], and giving (help) to kith and kin (i.e. all that Allâh has ordered you to give them e.g., wealth, visiting, looking after them, or any other kind of help)
Worship Allâh and join none with Him (in worship); and do good to parents, kinsfolk, orphans, Al-Masâkîn (the poor), the neighbour who is near of kin, the neighbour who is a stranger, the companion by your side, the wayfarer (you meet), and those (slaves) whom your right hands possess. Verily, Allâh does not like such as are proud and boastful.
It was authentically reported that the Prophet (peace be upon him) stated:
The best among you is the best toward his family and I am the best amongst you toward my family.
A Muslim should maintain good marital relationships and do good to relatives.As for
medical treatment expenses, the husband should assume this responsibility according to his means. This is based upon
...and live with them honourably.
And upon the generality of the above-mentioned Hadith.May Allah grant us success. May peace and blessings be upon our Prophet, his family and Companions.
