"We make indeed what is in the earth as an ornament for him, that we may test them who is best of his deeds"that is why they regard anything that exists in this world only as a trial that keeps them from their god, so they leave everything.

This verse is beautiful, it speaks to the heart.

Many scholars consider the angel Gabriel’s (as) three embraces during the first revelation to the Prophet (s.) a form of transmission

The following incident was related by Hazrat Alja bin Ka’b (R). “When I was in the mosque, a man came in and started to say his prayers. He recited the Holy Qur’an in a manner that appeared incorrect to me. Then another man came in and recited the Holy Qur’an in yet another way. I went to the Prophet (s.) and told him how these people had recited the Qur’an. The Prophet (s.) asked both men to recite the Holy Qur’an and they did. The Prophet (s.) then said that both were right. My heart was filled with evil doubt that was even stronger than that of the period of ignorance (jahiliyya). When the Prophet (s.) saw my state, he struck my breast with his hand. I started perspiring profusely and my state of fear and awe was such that I felt I was seeing God.

A story from the Buddhist Zen tradition:

A hermit was meditating by a river when a young man interrupted him. "Master, I wish to become your disciple," said the man. "Why?" replied the hermit. The young man thought for a moment. "Because I want to find God."
The master jumped up, grabbed him by the scruff of his neck, dragged him into the river, and plunged his head under water. After holding him there for a minute, with him kicking and struggling to free himself, the master finally pulled him up out of the river. The young man coughed up water and gasped to get his breath. When he eventually quieted down, the master spoke. "Tell me, what did you want most of all when you were under water."
"Air!" answered the man.
"Very well," said the master. "Go home and come back to me when you want God as much as you just wanted air."
