Hayyan Abu al-Nadr narrates that he met Sayyiduna Wathilah bin al-Asqa' (may Allah be pleased with him), and he said: I heard the Messenger of Allah (peace and blessings be upon him) say: "Allah, the Mighty and Majestic, says: I am as My servant thinks of Me; if he thinks well, then good, and if he thinks ill, then ill."
