This category refers to all those males whom a woman cannot marry at anytime in her life whatsoever. In other word a male who is forbidden permanently, forever (i.e. one’s father, brother or son etc)
Allah Ta’aala has given us a religion called Islam. Not just as a religion, but also as a complete way of life. A system of life which tackles and provides solutions for every immoral aspect of life and sets boundaries so that mankind does not exceed nor fall below the levels required to live a healthy, balanced and pure life and above all, a life in obedience to Allah. Anyone who has studied Islam in depth and seen the different aspects of life covered by Allah in the Qur’aan and by the Prophet (Sallallaahu alayhi wasallam) in Ahadeeth, will have no choice but to stand in awe and amazement as to how great and true these solutions of life are, that are taught to us by Islam.
One of the aspects of life covered in Islam is the interacting of males and females. As mentioned above, this aspect of life also has boundaries set in place. With certain things in life, there must be boundaries so that we can know the extent of what we can and cannot do since we are not wild and reckless but rather, civilised people. Also so that we know how far we can go in a matter before problems occur.
