The Holy Quran says,
“And one of His signs is that He has created for you, spouses from amongst yourselves so that you might take comfort in them and He has placed between you, love and mercy. In this there is surely evidence (of the truth) for the people who carefully think.” (Surah 30, Verse 21)

The Prophet (S) said, “One who marries, has already guarded half of his religion, therefore he should fear Allah for the other half.”
