When the Quraish saw that Islam was progressing day by day, they assembled before Waleed bin Mugheerah, who was one of their seniors and elders, and said, “The Haj season has almost arrived and your eminence is celebrated throughout the lands. People arriving from different lands will soon enquire from you regarding Rasulullah (sallallahu ‘alaihi wasallam). Hence, we need to unite and decide on one opinion regarding him, and we should all agree on this one opinion. We should not differ in our view regarding him, as this will lead to some of us contradicting others, and this will not be good for us.”
They then addressed Waleed bin Mugheerah saying, “O Abu ‘Abd-u-Shams! Why do you not decide on the opinion that we should all agree to regarding Rasulullah (sallallahu ‘alaihi wasallam)?” Waleed replied, “You first put your suggestions forward. I will listen, and I will thereafter decide on the opinion that we should have.
