Follow Islamic law regarding marriage; Be just and fair; Validate marriages with witnesses present; Respect marriage as an institution in Islam

This hadith is about the disapproval of secret marriages. Umar was a companion of Prophet Muhammad and one of the four rightly guided caliphs who ruled after him. In this hadith, Umar is presented as an example for us in how we should respond when we come across a situation where two people are married without witnesses present. He said that if he were the first person to come across such a situation then he would order them to be stoned. This shows us how seriously Islam takes marriage and how important it is for there to be witnesses present when two people get married so that their marriage can be validated by others in society. It also teaches us about justice and fairness - even though Umar was not personally affected by this situation, his response was still based on what was right according to Islamic law rather than personal opinion or bias.
