Follow Islamic principles and values; strive for justice and fairness towards others; follow teachings of Prophet Muhammad .

This hadith is about Uthman's ruling regarding the 'Iddah of a woman who was separated from her husband by Khul'. The Prophet Muhammad had previously ruled that Mariam Al-Maghaliyyah, who was married to Thabit bin Qais and was separated by Khul', should stay with him until she had menstruated. This same ruling applied to all women in similar situations, as Uthman followed this same principle when he gave his own judgement. The main values taught in this hadith are justice and fairness towards women, as well as following the teachings of Prophet Muhammad. It is important for us to remember that we should always strive to be just and fair in our dealings with others, especially those who are vulnerable or disadvantaged in any way. We must also remember that we should always follow the teachings of Prophet Muhammad so that we can live our lives according to Islamic principles and values.
