(1) The hadith is narrated from Muādh ibn Jabal—may Allah be pleased with him—in Sunan al-Tirmidhī, 4:124–125 (Book of Faith, chapter: “The Sanctity of Prayer”). It begins: “I was traveling with the Prophet—may Allah bless him and grant him peace—when I said, ‘O Messenger of Allah, tell me of a deed that will admit me to Paradise and keep me away from the Fire.’ He replied, ‘You have asked me about a momentous matter, yet it is easy for anyone for whom Allah makes it easy.’” The hadith also contains the words: “Charity extinguishes sin just as water extinguishes fire.” Al-Tirmidhī said: “This is a hasan sahih (good and authentic) hadith.” The hadith of Muādh is also narrated in Sunan Ibn Mājah, 2:1314–1315 (Book of Tribulations, chapter: “Restraining the Tongue during Tribulation”). These words also occur in another hadith, narrated from Ka'b ibn Ujra—may Allah be pleased with him—in Sunan al-Tirmidhī, 2:61–62 (Book of Friday Prayer: Travel, chapter: “The Virtue of Prayer”). It begins: “I seek Allah’s protection for you, O Ka'b ibn Ujra, from rulers who will come after me.” The hadith also contains the words: “Fasting is a shield, and charity extinguishes sin just as water extinguishes fire.” Al-Tirmidhī said: “This is a hasan gharīb (good but singularly transmitted) hadith.” These words also occur in a third hadith, narrated from Anas ibn Mālik—may Allah be pleased with him—in Sunan Ibn Mājah, 2:1408 (Book of Renunciation, chapter: “Envy”). It begins: “Envy consumes good deeds just as fire consumes firewood, and charity extinguishes sin just as water extinguishes fire.” The hadith of Muādh ibn Jabal is also found in al-Musnad, al-Halabī ed., 5:231, 237, 248, and the hadith of Ka'b ibn Ujra in al-Musnad, al-Halabī ed., 3:321, 399. (2) The hadith is narrated with some variation in wording from Abd Allāh ibn Amr ibn al-Ās—may Allah be pleased with them both—in Muslim, 3:1502 (Book of Governance, chapter: “One Who Is Killed in the Cause of Allah”); and al-Musnad, al-Maārif ed., 12 13.
