Chapter: The Statement of the Prophet: [Whoever is able to marry, should marry, for that will help him lower his gaze and guard his modesty (i.e. his private parts from committing illegal sexual intercourse etc.).’ And should a person marry (even if) he has no desire for marriage?] [Kitaabun Nikaah’ Saheeh Al-Bukhaari’ Hadeeth Number 5065]

Narrated ‘Alqamah:

“While I was with Abdullaah, uthman met him at Mina and said, ‘O Abu Abdur-Rahmaan! I have something to say to you.’ So both of them went aside and uthmaan said, ‘O Abu Abdur-Rahmaan! Shall we marry you to a virgin who will make you remember your past days? When Abdullaah felt that he was not in need of that, he beckoned me (to join him) saying, ‘O Alqamah’ Then I heard him saying (in reply to uthmaan), ‘As you have said that, (I tell you that) the Prophet (sallal-laahu-alayhi-wasallam) once said to us, ‘O young people! Whoever among you is able to marry, should marry, and whoever is not able to marry, is recommended to observe fast as fasting will diminish his sexual power’.

Imaam Abdul Azeez Bin Baaz [rahimahullaah] explains:

“Therefore, getting married is the correct [thing to do] as an obligation upon the one who has shahwa [sexual desires] even if he is not in fear of falling to Zinaa, and this is with regards to the one whose situation allows him to get married. This [also shows] Uthman’s righteous moral conduct and that the elderly person can get married as long as he has the strength for sexual relations; and those mainly intended in this hadeeth are the young people, because in most cases they possess greater desires and are more in need of that.”
