Narrated 'Umar (RA): The Prophet ( صلی اللہ علیہ وسلم ) said: "There is no (prostrations of) forgetfulness for one who is led (in prayer) by an Imam, but when the Imam forgets, both should then make prostrations due to forgetfulness." [al-Bazzar and al-Baihaqi reported it through a weak chain of narrators] .
