Surely We created man of the best stature ;
Then We reduced him to the lowest of the low ;
Save those who believe and do good works, and theirs is a reward unfailing.
Al Quran, At-Tin 95 : 4 - 6


Narrated Anas:
The Prophet said, "None of you will have faith till he wishes for his (Muslim) brother what he likes for himself."
Sahih Bukhari, Volume 1, Book 2, Number 12
