عَنْ جُبَيْرِ بْنِ مُطْعِمٍ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ لَا حِلْفَ فِي الْإِسْلَامِ وَأَيُّمَا حِلْفٍ كَانَ فِي الْجَاهِلِيَّةِ لَمْ يَزِدْهُ الْإِسْلَامُ إِلَّا شِدَّةً
It is narrated from Sayyiduna Jubair bin Mut’im (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: There is no mutual covenant in Islam, but any covenant or pact that was made in the pre-Islamic era of ignorance, Islam strengthens and reinforces it.
