Musannaf Ibn Abi Shayba 21:295

Ibn Numayr narrated to us, from Musa ibn Salim, from ‘Awn ibn ‘Abd Allah, from his father or from his brother, from al-Nu‘man ibn Bashir, who said: The Messenger of Allah (peace and blessings of Allah be upon him) said: "Those who mention the majesty of Allah, His glorification (tasbih), His praise (tahmid), His greatness (takbir), and His oneness (tahlil), they hover around the Throne, having a buzzing sound like the buzzing of bees, mentioning their companion. Would one of you not like to have something with the Most Merciful that mentions him?"
