Aisha (may Allah be pleased with her) narrates: I asked the Messenger of Allah (peace and blessings be upon him) about this verse: "Those who give what they give, and their hearts are fearful." I asked, "Are these the people who drink alcohol and steal?" The Prophet (peace and blessings be upon him) replied: "O daughter of the truthful one! No, rather they are those who fast, pray, and give charity, and they fear that it may not be accepted from them. It is they who hasten to good deeds." Hasan, narrated by Tirmidhi and Ibn Majah.
