He said: I also heard Abū Abd Allāh say: I heard Sufyān ibn Uyaynah say, “If someone is asked, ‘Are you a believer?’ he may decline to answer if he wishes; or, if he wishes, he may say, ‘Your asking me this is an innovation, and I do not doubt my faith.’ No one who says, ‘Faith decreases,’ or says, ‘If Allah wills,’ should be rebuked. This is not something he disapproves of, nor does it constitute doubt.”
