Hadith About Eman (Faith)

1. Islam is founded on five things: the testimony that there is no god but Allah and that Muhammad is His servant and messenger, the observance of the prayer, the payment of Zakah, the pilgrimage, and the fast during Ramadan.
(Bukhari, Muslim).

2. The Muslim is he from whose tongue and hand the Muslims are safe, and the Emigrant is one who abandons what Allah has prohibited.
(Bukhari). 

3. None of you believes (fully) until I, (Muhammad,) become dearer to him than his parents, his children and all other people.
(Bukhari, Muslim).

4. He who is not trustworthy has no Eman, and he who does not keep his Covenant has no Deen.
(Baihaqi).

5. What is Faith? When your good deed pleases you and your evil deed grieves you, you are a believer. What is Sin? When something disturbs (the peace of) your heart, give it up.
(Ahmad).
