Short answer
Islam encourages marrying early once you are able, both physically and financially, because it protects chastity. There is no fixed sunnah age. Delaying marriage for years for a career or a big wedding, while struggling to stay chaste, goes against the spirit of the sunnah. The four schools agree.
Marrying early is encouraged for anyone who has desire and the means to pay the mahr and provide, and it becomes wajib when he fears zina. There is no sunnah age: the ruling follows ability and need, not years.
The four schools agree on this.
Explanation
The Prophet ﷺ addressed young people directly: "O young people, whoever of you is able to marry, let him marry, for it lowers the gaze and guards chastity." The word he used, shabab, covers youth from puberty to around thirty. He did not name an age; he named a condition, ability.
What "able" means. Being able to pay the mahr, provide a home and basic support, and be a responsible spouse. Allah warns against setting the bar too high: "If they should be poor, Allah will enrich them from His bounty" (24:32). A modest life together is better than years alone waiting for a perfect one.
- Common delays: finishing every degree, building a career, buying a house, saving for a costly wedding, or family expectations about status.
- The harm: scholars warn that when families delay a ready young person until they fall into haram, the family shares the blame. The hadith warns of "fitnah on earth and great corruption" when good proposals are refused.
- Practical answers: a simple nikah, a small walimah, parents helping, or a nikah during studies with the couple moving in later.
Early does not mean rushed. Maturity, a good match and the ability to carry the responsibility matter as much as age. If you are not yet able, fast, keep busy and make dua. See the age of marriage, is marriage obligatory and dua for marriage.
The evidence
Quran, Surah An-Noor 24:32
وَأَنكِحُوا۟ ٱلْأَيَٰمَىٰ مِنكُمْ وَٱلصَّٰلِحِينَ مِنْ عِبَادِكُمْ وَإِمَآئِكُمْ ۚ إِن يَكُونُوا۟ فُقَرَآءَ يُغْنِهِمُ ٱللَّهُ مِن فَضْلِهِۦ ۗ وَٱللَّهُ وَٰسِعٌ عَلِيمٌۭ ﴿٣٢﴾
And marry the unmarried among you and the righteous among your male slaves and female slaves. If they should be poor, Allah will enrich them from His bounty, and Allah is all-Encompassing and Knowing.
Lack of wealth should not stop a ready person from marrying.
Sahih al-Bukhari 5065
Sahih... يا معشر الشباب من استطاع منكم الباءة فليتزوج ...
"O young people, whoever of you is able to marry, let him marry."
Young people who are able are told to marry.
Jami' at-Tirmidhi 1084
Grading to be checked... إلا تفعلوا تكن فتنة في الأرض وفساد عريض ...
"If you do not, there will be trial on earth and great corruption."
Refusing good proposals and delaying marriage harms society.
