عَنْ قَيْسِ بْنِ عَاصِمٍ أَنَّهُ سَأَلَ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ عَنِ الْحَلْفِ فَقَالَ مَا كَانَ مِنْ حَلْفٍ فِي الْجَاهِلِيَّةِ فَتَمَسَّكُوا بِهِ وَلَا حِلْفَ فِي الْإِسْلَامِ
It is narrated from Qais bin Asim that he asked the Holy Prophet, peace and blessings be upon him, about covenants and agreements. The Prophet, peace and blessings be upon him, said: Fulfill the covenants and agreements that you made during the time of ignorance, but in Islam, there are no such new covenants and agreements.
