Abu Malik al-Ashja‘i said: I said to my father, “Father, you have prayed behind God’s Messenger, Abu Bakr, ‘Umar and ‘Uthman, and behind Ali here in al-Kufa for about five years. Did they stand in humble supplication?” He replied, “Sonny, it is an innovation.” Tirmidhi, Nasa’i and Ibn Majah transmitted it.
