Rasulullah (sallallahu ‘alaihi wasallam) returned home after meeting Waraqah bin Nawfal. Thereafter, Rasulullah (sallallahu ‘alaihi wasallam) did not receive wahi for some time. The purpose of wahi being withheld was so that the initial fear that Rasulullah (sallallahu ‘alaihi wasallam) had perceived could cease and the desire of wahi could further increase.
When the wahi ceased for that period, Rasulullah (sallallahu ‘alaihi wasallam) became so saddened and grieved, due to the separation of the wahi that he had received, that he would repeatedly go to the top of the mountain so that he could throw himself off the peak. However, when this thought would cross his mind, Hazrat Jibreel (‘alaihis salaam) would immediately come to him and console him saying:
يا محمد إنك رسول الله حقا
O Muhammed (sallallahu ‘alaihi wasallam)! Indeed you are truly the messenger of Allah Ta‘ala!
On hearing these words, the blessed heart of Rasulullah (sallallahu ‘alaihi wasallam) would gain comfort and solace.
