Yazid narrated to us, he said: Abu Malik narrated to us, he said: "My father had prayed behind the Messenger of Allah, peace and blessings be upon him, when he was sixteen years old, and behind Abu Bakr, and Umar, and Uthman. So I said to him: Did they used to perform qunut? He said: No, my son, it is an innovation."
