Abu Hurairah quotes:

Allah makes the way to Jannah easy for him who treads the path in search of knowledge.

Avoid jealously for this destroys good deeds as fire destroys wood.

The Prophet (peace be upon him) said, 'The signs of a hypocrite are three: 1. Whenever he speaks, he tells a lie. 2. Whenever he promises, he always breaks it (his promise). 3. If you trust him, he proves to be dishonest (if you keep something as a trust with him, he will not return it).'
