حَدَّثَنَا أَبُو تَوْبَةَ الرَّبِيعُ بْنُ نَافِعٍ حَدَّثَنَا مُعَاوِيَةُ بْنُ سَلَّامٍ عَنْ يَحْيَی بْنِ أَبِي کَثِيرٍ قَالَ أَخْبَرَنِي أَبُو قِلَابَةَ أَنَّ ثَابِتَ بْنَ الضَّحَّاکِ أَخْبَرَهُ أَنَّهُ بَايَعَ رَسُولَ اللَّهِ صَلَّی اللَّهُ عَلَيْهِ وَسَلَّمَ تَحْتَ الشَّجَرَةِ أَنَّ رَسُولَ اللَّهِ صَلَّی اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ مَنْ حَلَفَ بِمِلَّةٍ غَيْرِ مِلَّةِ الْإِسْلَامِ کَاذِبًا فَهُوَ کَمَا قَالَ وَمَنْ قَتَلَ نَفْسَهُ بِشَيْئٍ عُذِّبَ بِهِ يَوْمَ الْقِيَامَةِ وَلَيْسَ عَلَی رَجُلٍ نَذْرٌ فِيمَا لَا يَمْلِکُهُ
سنن ابودوٗد · Hadith 3257
Narrated Thabit bin Adh-Dahhak: That he took oath of allegiance to the Messenger of Allah ﷺ under the tree. The Messenger of Allah ﷺ said: If anyone swears by religion other than Islam falsely, he is like what has has said. If anyone kills himself with something, he will be punished with it on the Day of Resurrection. A vow over which a man has no control is not binding on him.
