Sayyiduna Mu'awiyah bin Haydah (may Allah be pleased with him) narrates that the Prophet (peace and blessings be upon him) said: "Giving charity in secret extinguishes the anger of the Lord."
Al-Tabarani recorded it in al-Mu'jam al-Kabir and al-Mu'jam al-Awsat as a longer narration than this. That long narration will come later in the chapter on righteousness, if Allah wills. The chain of this narration contains a narrator, Sadaqah bin Abdullah, whom Duhaym declared thiqah (trustworthy), while a group declared him da'if (weak).
