Gulf Arab muslim man's shoulder problem revealed

while standing in line to pay my phone bill, I got a strong word of knowledge for the muslim man who was behind the counter. I asked him what was wrong with his left shoulder. He began to tell me about an injury he had lifting weights. I asked him after a minute, "Do you know how I knew you had a shoulder problem"? He said, "No, how?". I shared with him that God reveals what he want to heal. I then prayed a quick prayer for his shoulder. He couldn't tell if there was a difference, but took my phone number. I told him I would love to meet him again to tell him more about healing.
