Imam Ja‘far al-Ṣadiq (as): It is written in the Torah: O son of Adam, Be as you would like to be; as you give so shall you get. One who accepts from Allah the little livelihood, Allah will accept from him the little in actions [worships]. One who is content with a little of lawful sustenance, his burden will be light, his earnings will be pure and will exit the limits of wickedness. al-Kāfī
