Yes, it is an important Sunnah of our beloved Prophet ﷺ. Marriage makes a person complete according to the Prophetic hadith.
Beloved Prophet ﷺ said:
“Marriage is part of my sunnah, and whoever does not follow my sunnah has nothing to do with me. Get married, for I will boast of your great numbers before the nations. Whoever has the means, let him get married, and whoever does not, then he should fast for it will diminish his desire.” (Ibn Majah)
Beloved Prophet ﷺ also said:
“When a man gets married, he gets one half of the religion. Thus, he should fear Allah in the other half.” (Baihaqi)
