An excerpt from “From Sarah With Pain” (a by-now-very-dead project I worked on back in 2008);
You know, once upon a time, I used to love the word ‘family’ until I discovered that most family members took their kinship for granted; people who think that they have the right to hurt somebody just because they are related to them; people who stamp on each other for the sake of materialistic gains; people who no longer respect the word, ‘family’, and maybe I am the same, but I’m neither the first person nor the person to be like that.
Following up on Relationships worth fighting for, let’s focus today on family. The equations of family relationships are supposed to be the easiest in the sense that you tend to carry unconditional love for people who are related to you by blood, right? Also in Islam, upholding the ties of kinship is obligatory, and it is explained by the Messenger (peace and blessings of Allaah be upon him) when he said: “The one who maintains a relationship with his relatives only because they maintain a relationship with him is not truly upholding the ties of kinship. The one who truly upholds those ties is the one who does so even if they break off the relationship.” (Reported by al-Bukhaari, 5645). 
When people are younger, they may respect the word ‘family,’ defending their siblings when they get into trouble so they end up into trouble together, but as they grow older something happens. Maybe it has something to do with “Familiarity Breeds Contempt” (or to be more exact, “Family Breeds Contempt”). Maybe other people enter the equation in the form of wives-husbands-in-laws and result in disequilibrium. Or maybe they decide to put their money together in the form of a family business, which puts one of two things at risk; either the business or the relationship. Or maybe they just grow up and grow apart, developing their different personalities that act like sodium and water, so that the status of the relationship disintegrates with time.
Whatever the reason, I don’t think it’s justified, because in the end family is family, and upholding ties of kinship is a religious kinship.
