'Abdullah ibn Mas'ood (May Allah be pleased with him) reported
from the Prophet (sallallahu alayhe wa salam) that he said:
"A person who has an atom's weight of pride (kibr)
in his heart will not enter Paradise".
A person asked: "But one does like to wear good clothes and shoes!"
The Prophet (sallallahu alayhe wa salam) replied:
"Indeed Allah is beautiful and loves beauty!
Pride means to reject the truth and to look down on others!"
