Musannaf Ibn Abi Shayba 33:1153

'Affan narrated to us, he said: Hammad bin Salamah narrated to us, from Thabit, he said: Abu 'Uthman al-Nahdi said: "I indeed know when my Lord remembers me." They said: "And how is that?" He said: "Indeed, Allah says: 'So remember Me, I will remember you.' So when I remember Allah, He remembers me."
