Ibn Taymiyah 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 Allaah (peace and blessings of Allaah 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 Allaah be upon him) enjoined when the Muhaajiroon asked him which kind of wealth they should acquire, and he said: “Let one of you acquire a tongue that remembers Allaah, a thankful heart, and a believing wife who will help him with regard to the Hereafter.” Narrated by al-Tirmidhi from Saalim ibn Abi’l-Ja’d, from Thawbaan.
She may offer the love and compassion that Allaah 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.”
