He (the Messenger of Allah) loved to repeat the supplication thrice. He was saying: O Allah, it is for Thee to deal with the Quraish (repeating these words thrice). And among the Quraish, he mentioned (the names of) al-Walid b. 'Utba and Umayya b. Khalaf. (The narrator says there is no doubt about the names of these persons but he has forgotten the name of the seventh man).
