(5) The report comes from Abu Said al-Khudri who said: “We asked, ‘Messenger of Allah, we already know how to greet you; but how do we invoke blessings upon you?’ He replied, ‘Say …’ ”—and he cited the formula. It is recorded by al-Bukhari (8/432–433; 11/138); al-Nasa i (1/190–191); and, through him, by Ibn al-Sunni (124); Ibn Majah (1/292–293); al-Tahawi (3/73); al-Bayhaqi (2/147); Ahmad (3/47); and—according to my critical edition—by Ismail al-Qadi in Fadl al-salat ala al-nabi (p. 28, 1st ed.; p. 62, 2nd ed., Maktab al-Islami). All of them transmit it through various chains from Yazid b. Abd Allah b. al-Had, from Abd Allah b. Khabbab, from Abu Said. The first additional phrase appears in one narration of al-Bukhari. The second is found in al-Tahawi and likewise in one manuscript of al-Bayhaqi. The remaining sources give, in its place, the third addition. The fourth addition is reported only by al-Bukhari, Ahmad, and Ismail al-Qadi.
