Sayyiduna Sa'd bin Abi Waqqas (may Allah be pleased with him) relates: This verse was revealed about me: "O you who believe! When you consult the Messenger privately, present an offering of charity before your private consultation." So I presented a grain of barley. The Prophet (peace and blessings be upon him) said: "You are indeed one who gives very little." Then the other verse was revealed: "Are you afraid to present offerings of charity before your private consultation?" This is the complete verse.
Al-Tabarani recorded it within a long hadith; and in the hadith of the Sahih it is mentioned: "Three verses were revealed about me." Its chain contains a narrator, Salamah bin al-Fadl al-Abrash, whom Yahya bin Ma'in and others declared thiqah (trustworthy), while al-Bukhari (may Allah have mercy on him) and others declared him da'if (weak).
