Islamic Marriage

وَأَنكِحُوا الْأَيَامَى مِنكُمْ وَالصَّالِحِينَ مِنْ عِبَادِكُمْ وَإِمَائِكُمْ؛ نور:32

Get married and do not divorce, since divorce makes the Divine Throne tremble.[1]

If a virgin or a woman refuses to marry no one has the permission to oblige her, even if the marriage formula (Sigha) is pronounced the marriage is invalid until she agrees.

Summary:Some say Islam has fixed the marriage age for boys at 15 years and that of girls at the age of nine years. This is not correct. Islam has not given any such order. Islam is the religion of nature and gives an order against nature and human instinct. But Islam commands one to marry when one reaches puberty and maturity. According to the interpretation of the Prophet (peace be upon him) it is like a fruit whose ripening is its maturity and adult age.

"النِّکاحُ سُنَّتِي، فَمَن رَغِبَ عَن سُنَّتي فَلَیسَ مِنّي"
"Marriage is my sunnah (tradition). Whosoever does not follow my sunnah is not from me."

Summary:
"وَمِنْ آیَاتِهِ أَنْ خَلَقَ لَکُمْ مِنْ أَنفُسِکُمْ أَزْوَاجًا لِتَسْکُنُوا إِلَیْهَا وَجَعَلَ بَیْنَکُمْ مَوَدَّهً وَرَحْمَهً إِنَّ فِی ذَلِکَ لَآیَاتٍ لِقَوْمٍ یَتَفَکَّرُون"
"And one of His signs is that He created mates for you from yourselves that you may find rest in them, and He put between you love and compassion; most surely there are signs in this for a people who reflect"
There are several points here.
