Qatadah narrates: When someone came to Sayyiduna Uthman (may Allah be pleased with him) to call him to the prayer, he would say: "Welcome to those who speak with justice, and welcome to the prayer, and greetings."
Imam al-Tabarani recorded it in al-Mu'jam al-Kabir; the narrator Qatadah did not hear from Sayyiduna Uthman (may Allah be pleased with him).
