Marriage is the Sunnah of the Prophets

وَلَقَدْ أَرْسَلْنَا رُسُلًۭا مِّن قَبْلِكَ وَجَعَلْنَا لَهُمْ أَزْوَٰجًۭا وَذُرِّيَّةًۭ ۚ وَمَا كَانَ لِرَسُولٍ أَن يَأْتِىَ بِـَٔايَةٍ إِلَّا بِإِذْنِ ٱللَّهِ ۗ لِكُلِّ أَجَلٍۢ كِتَابٌۭ

We did send messengers before thee, and appointed for them wives and children: and it was never the part of a messenger to bring a sign except as Allah permitted (or commanded). For each period is a Book (revealed).
