The face of Jibreel (May peace be upon him) on the heel of the Holy Prophet (Sallallahu alaihi wa sallam)
The night of Meraj, the Holy Prophet (Sallallahu alaihi wa sallam) had the honor of serving the Holy Prophet (Sallallahu alaihi wa sallam), as given in Tafseer Ruh Al Bayan, Vol. 5, Pg. No. 109:
Translation: The night of Meraj, Jibreel, Mikail, Israfeel and Izrail (May peace be upon them) all came. Each one of them had 70,000 angels. When the Holy Prophet (Sallallahu alaihi wa sallam) mounted the Burraq, Jibreel (May peace be upon him) held the reins, Mikail (May peace be upon him) held the stirrup and Israfeel (May peace be upon him) held the saddle.
It is in the night of Meraj that we find the highest form of reverence of the Holy Prophet (Sallallahu alaihi wa sallam) of Jibrel (May peace be upon him).
Mulla Muhammad Moin Kaashfi Haravi (May Allah Ta'ala shower His mercy on him) narrates a Hadith about Meraj:
Translation: The second narration is from Jibreel (May peace be upon him): I got to know from the Wahi of Allah Ta'ala that my body has been fashioned out of camphor of Jannah, but I didn’t know the reason for this. I realized this on the night of Meraj. In spite of my purity and fineness, I was hesitating to awaken the Holy Prophet (Sallallahu alaihi wa sallam) and I was anxious as to how should I do it. I was ordered that I should rub my face on the heel of the blessed foot of the Holy Prophet (Sallallahu alaihi wa sallam). When I did so, the coolness of camphor met the warmth (of the feet of the Holy Prophet (Sallallahu alaihi wa sallam)) and the Holy Prophet (Sallallahu alaihi wa sallam) easily awakened from sleep. At that time, I realized the reason of me being created from camphor. (Ma’arij Un Nubuwwah, Pg. No. 601)
