“I have studied over seventy-one different books. After reading all of them I have come to the conclusion that from the first man to the last, the intelligence which was given to the entire humanity when compared to the intelligence of the Prophet Muhammad (peace and blessing be upon him) is like that of a grain of sand compared to the sand of the entire world.
He was indeed the most intelligent man ”
The Prophet of Allah (peace and blessing be upon him) said to Ayesha (may Allah be pleased with her):
“I can well discern when you are pleased with me and when you are annoyed with me.”
She, may Allah be pleased with her, asked, “How do you discern it?”
Thereupon the Prophet (peace and blessing be upon him) replied: “When you are happy with me you take an oath saying, ‘I swear by the Lord of Muhammad. However, when you are upset you would say, ‘I swear by the Lord of Ibrahim.”
Ayesha (may Allah be pleased with her), said: “Yes (you are right) O Messenger of Allah, but by Allah, I leave nothing but your name.”
