Sayyiduna Mu'adh bin Jabal (may Allah be pleased with him) narrates that the Prophet (peace and blessings be upon him) said: "I shall tell you about some of the gates of goodness: fasting is a shield; charity extinguishes sins just as water extinguishes fire; and the servant's standing in prayer in the middle of the night." Then he recited this verse: "Their sides forsake their beds" (to the end of) the verse.
Ahmad recorded it, and Shahr bin Hawshab did not hear from Sayyiduna Mu'adh (may Allah be pleased with him).
