AbuBakr adjured the Prophet ﷺ. The Prophet ﷺ said: Do not adjure an oath.  

أَنَّ أَبَا بَكْرٍ أَقْسَمَ عَلَى النَّبِيِّ ﷺ فَقَالَ لَهُ النَّبِيُّ ﷺ لاَ تُقْسِمْ  

Abu Hurairah narrated that a man came to the Messenger of Allah ﷺ and said: I had a dream last night, and he then mentioned it. So Abu Bakr interpreted it. The Prophet ﷺ said: You are partly right and partly wrong. He then said: I adjure you, Messenger of Allah, may my father be sacrificed on you, do tell me the mistake I have committed. The Prophet ﷺ said: Do not adjure.  

أَنَّ رَجُلاً أَتَى رَسُولَ اللَّهِ ﷺ فَقَالَ إِنِّي أَرَى اللَّيْلَةَ فَذَكَرَ رُؤْيَا فَعَبَّرَهَا أَبُو بَكْرٍ فَقَالَ النَّبِيُّ ﷺ أَصَبْتَ بَعْضًا وَأَخْطَأْتَ بَعْضًا فَقَالَ أَقْسَمْتُ عَلَيْكَ يَا رَسُولَ اللَّهِ بِأَبِي أَنْتَ لَتُحَدِّثَنِّي مَا الَّذِي أَخْطَأْتُ فَقَالَ النَّبِيُّ ﷺ لاَ تُقْسِمْ  

"He did not inform him."  

عَنِ النَّبِيِّ ﷺ بِهَذَا الْحَدِيثِ لَمْ يَذْكُرِ الْقَسَمَ زَادَ فِيهِ وَلَمْ يُخْبِرْهُ
