When humans are living in luxury, they begin to think it is their right to have it. But it is from Allah, and you must be happy and thankful with what He gives you. Now, instead of poverty, people complain about their marriage; saying the love is not like at the beginning. This is a sign of very low īmān. Marriage is an institution that Allāh ﷻ and the Prophet ﷺ like. The family institution is holy. Marriage is one of the foundations of Islām. Always think for your marriage to continue and to be accepted in the Divine Presence.
