Oaths and Vows — Hadith #1558
وَعَنْ أَبِي هُرَيْرَةَ - رضى الله عنه - قَالَ: قَالَ رَسُولُ اَللَّهِ - صلى الله عليه وسلم -{ " يَمِينُكَ عَلَى مَا يُصَدِّقُكَ بِهِ صَاحِبُكَ" } وَفِي رِوَايَةٍ: { "اَلْيَمِينُ عَلَى نِيَّةِ اَلْمُسْتَحْلِفِ" } أَخْرَجَهُمَا مُسْلِمٌ 1 .1 - صحيح رواه مسلم ( 1653 ).
Allah’s Messenger (ﷺ) said: “Your oath will be about that matter which your adversary has required you to swear about so that he will believe you.”
In another narration: “An oath is to be interpreted according to the intention of the one who requested it (Al-Mustahlif).”
