Sahih Muslim
The Book Pertaining to Paradise, Its Description, Its Bounties and Its Intimates (Kitab Al-Jannat wa Sifat Naimiha wa Ahliha)
Book Number: 040 / Hadith Number: 6835
Haritha b. Wahb al-KhuzaIi reported Allah's Messenger (may peace be upon him) as saying: May I not inform you about the inmates of Paradise? (And then informing about them) said: Every meek person who is considered to be humble and if they were to adjure in the name of Allah, Allah would certainly fulfil it. May I not inform you about the inmates of Hell-Fire? They are all proud, mean and haughty.
