´It was narrated from Anas that:` The Messenger of Allah (ﷺ) said the Qunut for one month, supplicating against one of the 'Arab tribes, then he stopped doing that."
´It was narrated from Abu Malik Al-Ashja'i that his father said:` "I prayed behind the Messenger of Allah (ﷺ) and he did not say the Qunut, and I prayed behind Abu Bakr and he did not say the Qunut, and I prayed behind Umar and he did not say the Qunut, and I prayed behind Uthman and he did not say the Qunut, and I prayed behind Ali and he did not say the Qunut." Then he said: "O my son, this is an innovation."
