question #1 Sahih al-Bukhari 1636, Book 25, Hadith 119 : What is the significance of the event where the Prophet’s chest was opened and filled with Wisdom and Belief?

Allah’s Messenger (ﷺ) said, “The roof of my house was made open while I was at Makkah (on the night of Mi’raj) and Jibril descended. He opened up my chest and washed it with the water of Zamzam. The he brought the golden tray full of Wisdom and Belief and poured it in my chest and then closed it. The he took hold of my hand and ascended to the nearest heaven. Jibril told the gatekeeper of the nearest heaven to open the gate. The gatekeeper asked, “Who is it?” Jibril replied, “I am Jibril.” (See Hadith No. 349 Vol.1)
