During the negotiations, Uthman ibn Affan was chosen as an envoy to convene with the leaders in Mecca, on account of his high regard amongst the Quraysh.[39] On his entry into Mecca, rumours ignited that Uthman had subsequently been murdered by the Quraysh. Muhammad responded by calling upon the pilgrims to make a pledge not to flee (or to stick with Muhammad, whatever decision he made) if the situation descended into war with Mecca. This pledge became known as the "Pledge of Good Pleasure" (Arabic: بيعة الرضوان, bay'at al-ridhwān) or the "Pledge under the Tree".[38]
