Musannaf Ibn Abi Shaybah

Hazrat Awam says that I heard Ibrahim al-Taimi saying: When a servant says, "All praise is for Allah, and Allah is free from all defects," the angels say: "And along with His praise." Then when the servant says, "Allah is free from all defects and is with His praise," the angels say: "May Allah have mercy on you." Then when the servant says, "Allah is the Greatest," the angels say: "Very great." Then when the servant says, "Allah is greater than all," the angels say: "May Allah have mercy on you." Then when the servant says, "All praise is for Allah," the angels say: "The Lord of all the worlds as well." And when the servant says, "The Lord of all the worlds as well," the angels say: "May Allah have mercy on you."
