Obey Allah's commands , Follow teachings of Prophet Muhammad , Be just and fair .

This hadith is about the prohibition of temporary marriage in Islam. Umar bin Khattab was appointed as the second caliph after Prophet Muhammad's death and he addressed his people warning them against entering into temporary marriages. He said that if he heard of anyone doing so, he would stone them to death unless they could bring him four witnesses who would testify that Prophet Muhammad had allowed it after forbidding it. This shows us how important following Allah's commands are in Islam and how serious a crime disobeying Him is considered to be. It also teaches us about justice and fairness as Umar bin Khattab was willing to accept evidence from four witnesses before punishing someone for breaking Allah's law.
