"When 'Umar bin Khattab was appointed caliph, he addressed the people and said: 'The Messenger of Allah permitted temporary marriage for us three times, then he forbade it. By Allah, If I hear of any married person entering a temporary marriage, I will stone him to death, unless he can bring me four witnesses who will testify that the Messenger of Allah, allowed it after he forbade it'."
إِنَّ رَسُولَ اللَّهِ ﷺ أَذِنَ لَنَا فِي الْمُتْعَةِ ثَلاَثًا ثُمَّ حَرَّمَهَا وَاللَّهِ لاَ أَعْلَمُ أَحَدًا تَمَتَّعَ وَهُوَ مُحْصَنٌ إِلاَّ رَجَمْتُهُ بِالْحِجَارَةِ إِلاَّ أَنْ يَأْتِيَنِي بِأَرْبَعَةٍ يَشْهَدُونَ أَنَّ رَسُولَ اللَّهِ أَحَلَّهَا بَعْدَ إِذْ حَرَّمَهَا
