Although marriage is generally considered a highly recommended act, from the Islamic point of view marriage differs according to the state and conditions of each person: It can be highly recommended in some cases, or even obligatory under certain conditions. It can also be prohibited or only permitted under other circumstances.
Sheikh Ahmad Kutty, a senior lecturer and Islamic scholar at the Islamic Institute of Toronto, Ontario, Canada , states the following: The precise status of marriage in Islam varies according to the person and their circumstance. In other words, marriage is obligatory on those who are unable to control their desires and are afraid of falling into sin; it is recommended for all those who have desire for union and yet do not fear falling into sin; it is undesirable for those who have no desire and are afraid of fulfilling their spousal obligations; and it is clearly forbidden for those who have no desire whatsoever and are incapable of doing justice, and may end up harming or injuring their partners. An example is someone who has a sexually transmitted disease which they may end up passing to others if they get married.
To conclude: If one belongs to the category of those who have no desire for union, and they feel they cannot fulfill the spousal obligations, then there is nothing wrong for them to remain a celibate. That decision is solely theirs, and parents have no right to force anyone to get married. May Allah help us see truth as truth and follow it, and may He help us to see error as error and shun it—ameen.
