Respect marriage and do not take decisions related to it lightly; Consider all implications before entering into or ending a marriage; Be mindful when declaring an irrevocable divorce as this has far-reaching consequences.

This hadith is about the importance of divorce and how it should not be taken lightly. Umar ibn Abd al-Aziz asked Aban ibn Uthman what people said about the 'irrevocable' divorce, to which he replied that it was declared only once. Umar then stated that even if a person were to declare divorce a thousand times, the 'irrevocable' would use them all up. This shows how serious this type of divorce is and how it should not be done without thought or consideration for its consequences. It also highlights the importance of marriage in Islam as something that should not be entered into lightly or ended without due consideration for its implications on both parties involved.
