If Rasulullah (sallallahu ‘alaihi wasallam) received divine revelation whilst mounted upon a camel, the camel would be forced to sit due to the weight of the wahi. Hazrat Zaid bin Thaabit (radhiyallahu ‘anhu) narrates, “On one occasion, the blessed thigh of Rasulullah (sallallahu ‘alaihi wasallam) was on my thigh when he started receiving divine revelation. His thigh became so heavy that I was afraid of my thigh being crushed.”
