When the Prophet ﷺ ordered a man and his wife to invoke curses on each other, he ordered a man to put his hand on his mouth when he came to the fifth utterance, saying that it would be the deciding one.  

أبو داود:٢٢٥٥حَدَّثَنَا مَخْلَدُ بْنُ خَالِدٍ الشَّعِيرِيُّ حَدَّثَنَا سُفْيَانُ عَنْ عَاصِمِ بْنِ كُلَيْبٍ عَنْ أَبِيهِ عَنِ ابْنِ عَبَّاسٍ

أَنَّ النَّبِيَّ ﷺ أَمَرَ رَجُلاً حِينَ أَمَرَ الْمُتَلاَعِنَيْنِ أَنْ يَتَلاَعَنَا أَنْ يَضَعَ يَدَهُ عَلَى فِيهِ عِنْدَ الْخَامِسَةِ يَقُولُ إِنَّهَا مُوجِبَةٌ
