Be truthful in marriage commitments; use divorce only as an absolute last resort; respect testimony in Islamic law; follow rulings given by Prophet Muhammad (ﷺ) .

This hadith is about a case of Lian which was witnessed by Sahl bin Sa'd when he was fifteen years old. In this case, the Prophet (ﷺ) ordered that they be divorced and the husband said "If I kept her, I would be a liar". Az-Zubair then stated that if the woman gave birth to a child with certain description then her husband would prove truthful and if she gave birth to another type of child then he would prove untruthful. This hadith teaches us about truthfulness in marriage and how it should not be taken lightly as it can have serious consequences for both parties involved. It also teaches us about divorce in Islam and how it should only be used as an absolute last resort when all other options have been exhausted. Furthermore, this hadith highlights how important testimony is in Islamic law as it can help determine whether someone is telling the truth or not.
