The day of Buath was a day that Allah arranged in advance for His Messenger ﷺ. By the time the Messenger of Allah ﷺ arrived, their leadership had splintered, their nobles had been killed, and many had been wounded. Allah arranged this in advance for His Messenger ﷺ to pave the way for their entry into Islam.
حدثني عبيد بن إسماعيل حدثنا أبو أسامة عن هشام عن أبيه
كان يوم بعاث يوما قدمه الله لرسوله ﷺ فقدم رسول الله ﷺ وقد افترق ملؤهم وقتلت سرواتهم وجرحوا قدمه الله لرسوله ﷺ في دخولهم في الإسلام
