In order to test him, those who had been to Bayt-ul-Muqaddas began to question him about the distinguishing features of Bayt-ul-Muqaddas. At that time, Allah Ta‘ala brought Bayt-ul-Muqaddas right before his very eyes. The disbelievers then began to pose their questions, and Rasulullah (sallallahu ‘alaihi wasallam) answered them while seeing Bayt-ul-Muqaddas.

Eventually, when all their questions pertaining to Bayt-ul-Muqaddas were exhausted, they asked, “Okay, tell us some incident about the road leading to Bayt-ul-Muqaddas.” Rasulullah (sallallahu ‘alaihi wasallam) replied, “On my way, I came across a trade caravan at a certain place that was returning to Makkah Mukarramah from Syria. They lost one camel and later retrieved it. Insha Allah, this trade caravan should reach Makkah Mukarramah within three days. At the front of the caravan will be a dust-colored camel laden with two sacks of goods.”

Accordingly, on the third day, this caravan entered Makkah Mukarramah in precisely the same manner which Rasulullah (sallallahu ‘alaihi wasallam) had foretold, and they also narrated the incident of the lost camel. On seeing and hearing this, Waleed bin Mugheerah dismissed the whole incident by declaring, “This is nothing but sorcery.” The people also concurred with him saying, “Yes, Waleed is speaking the truth.”
