The Messenger صلى الله عليه وسلم said: “A righteous wife to help you with your worldly and religious affairs is the best treasure anyone could have.” [Al-Bayhaqī, Saheeh al-Jāmī, 4285]
Shaykh Salīh Al-Fawzan said: “If a man is married with a righteous wife, he (will) live a harmonious life even if he is poor.” [Al-Ittihaf, pg. 858]
A righteous wife will be with her righteous husband for many years.
Shaykh al-Islam Ibn Taymīyyah (may Allāh have mercy on him) said:
“A righteous wife will be with her righteous husband for many years, and she is the one who is meant in the hadeeth in which the Messenger of Allāh (peace and blessings of Allāh be upon him) said: “This world is temporary conveniences and the best of its comforts is a believing wife, who when you look at her she pleases you and if you tell her to do something she obeys you, and if you are away from her she protects you with regard to herself and your wealth.”
This is what the Prophet (peace and blessings of Allāh be upon him) enjoined when the Muhājiroon asked him which kind of wealth they should acquire, and he said: “Let one of you acquire a tongue that remembers Allāh, a thankful heart, and a believing wife who will help him with regard to the Hereafter.”
[Narrated by al-Tirmidhī from Salim ibn Abī ’l-Ja’d, from Thawbān]
She may offer the love and compassion that Allāh speaks of in His Book, and the pain of separation may be harder for her than death in some cases, and harder than losing wealth or leaving one’s homeland, especially if one of them is fond of the other or they have children together who will be harmed by separation.
[Majmoo’ al-Fatāwa, 35/299]
Prophet Muhammad صلى الله عليه وسلم said: “A woman may be married for four reasons: her wealth, her lineage (family status), her beauty or her religious commitment; choose the one who is religious and you will prosper.” [Sahīh Bukharī, Book 62, Hadīth Number 27]
