"Your oath is as your companion understands it to be." (Using translation from Ibn Mājah 2121)  

أحمد:٨٣٧٨حَدَّثَنَا أَبُو النَّضْرِ حَدَّثَنَا أَبُو عَقِيلٍ اسْمُهُ عَبْدُ اللهِ بْنُ عَقِيلٍ الثَّقَفِيُّ ثِقَةٌ حَدَّثَنَا عَبْدُ اللهِ بْنُ سَعِيدٍ عَنْ أَبِيهِ عَنْ أَبِي هُرَيْرَةَ قَالَ

قَالَ رَسُولُ اللهِ ﷺ يَمِينُكَ مَا يُصَدِّقُكَ بِهِ صَاحِبُكَ
