Faith is firm belief and good actions

Al-Hasan Al-Basri – Allah have mercy on him – said:

Faith (iman) is not by embellishment or wishful thinking, but it iswhat settles in the heart and is verified through your works.Whoever says good but does not do good will have his words compared to his deeds by Allah. Whoever says good and doesgood will have his words raised by his deeds.

This is because Allah ‘azza wa jalla said:To Him ascends the good word, and the righteous deedraises it. [Sûrah Fâtir: 10]
