Adab al-Mufrad

Benefits and Issues:
➊ Just as caring for daughters and treating them well is a means of entering Paradise, so too is the care and good treatment of sisters. Socially, we observe that after marriage, brothers generally do not treat their sisters well. Especially if the parents have passed away and the sisters are still unmarried, they are not treated as well. Brothers, following the words of their wives, do not treat their sisters kindly. It is also observed that while brothers work day and night to provide for their wives and children, their sisters have to work themselves to make ends meet and for their own marriages. Islam discourages this and encourages that just as your daughters are deserving of good treatment, so too are your sisters—especially when they are deprived of the shade of their father's affection, they are in need of your kindness. When the father of Sayyiduna Jabir radi Allahu anhu passed away, his sisters were young. Sayyiduna Jabir radi Allahu anhu married a previously married woman so that she could raise his sisters in the best manner. When the Messenger of Allah sallallahu alayhi wa sallam asked Jabir radi Allahu anhu why he did not marry a virgin, he replied that he married a previously married woman for the sake of raising his sisters. The Prophet sallallahu alayhi wa sallam praised him for this, from which it is understood that after the loss of the father, it is the responsibility of the brothers to arrange for the upbringing and care of their sisters.

➋ Sisters naturally love their brothers more, whereas brothers do not care for them as much. Therefore, the Messenger of Allah sallallahu alayhi wa sallam, through this statement, encouraged that if sisters are in need, taking care of their needs is also a source of reward. In one narration (Abu Dawud: 5148), the same virtue is mentioned for the one who cares for two sisters.
