I don't want to get married ever. I am a Muslim boy who knows marriage is Sunnah, but I just don't want to spend my life raising kids. I want to travel the world, write books and remain single. I am not the kind of person who wants to get tied down and voluntarily take responsibilities. I want to travel for life. Would that be okay?
Allah said in Quran (what means):
وَمِنْ آيَاتِهِ أَنْ خَلَقَ لَكُم مِّنْ أَنفُسِكُمْ أَزْوَاجًا لِّتَسْكُنُوا إِلَيْهَا وَجَعَلَ بَيْنَكُم مَّوَدَّةً وَرَحْمَةً ۚ إِنَّ فِي ذَٰلِكَ لَآيَاتٍ لِّقَوْمٍ يَتَفَكَّرُون
"And among His signs is this, that He created for you wives from among yourselves, that you may find repose in them, and He has put between you affection and mercy. Verily, in that are indeed signs for a people who reflect. (21)"
[Quran, Chapter 30, verse 21]
Prophet Muhammad (PBUH) said:
النکاح من سنتی فمن رغب عن سنتی فلیس منی
Marriage is my sunnah and who ever turns away from my sunnah is not of me
Nikaah (Marriage) is Prophet (PBUH)'s permanent sunnah. It is a great sin for a person who can marry but don't marry.
There are more benefits in getting married than being single.
This my PERSONAL opinion: I don't think that it's a must for you to get married. Oh and for all the people who are using this hadith;'Marriage is my sunnah and who ever turns away from my sunnah is not of me' It's about those people who can afford marriage and still don't proceed doing so just because they believe it will reduce their wealth, or putting it simply, it's for those people who don't get married because they don't want to spend any money and all that. Besides, if you can handle yourself independently and don't wish to get married, then there is no need to get married. And anyways, Islam states that nobody (even parents) can not force anyone into marriage, the relationship will only be then officially connubial if both the girl and boy agree to it. But you must keep in mind that if you want to fulfill your sexual desires then you'll have to get married as Islam doesn't allow sexual relationships with anyone except your wife/husband.
