I thought he was befuddled, when he was coming afar! But I got he was crazy when came near me.  He  was looking around himself and murmuring  something.

For justification of his uncommon behaviors, I said to Prophet Muhammad (pbuh &h), “He is crazy.”

Prophet Muhammad (pbuh &h) glimpsed at me and stated, “ He is not crazy.”

I asked surprisingly,” Isn’t he crazy?”
Prophet Muhammad (pbuh &h) stated that he was not crazy but was sick. He stated,”A crazy person is one who is arrogant and inflated.”

“And swell not thy cheek (for pride) at men, nor walk in insolence through the earth; for Allah loveth not any arrogant boaster. (Surah Luqman, verse18).
