Musannaf Ibn Abi Shaybah 4940 — A man standing in prayer who hears

Abu Ishaq said: I was standing beside Abdullah bin Ma'qil while he was praying and reciting Surah al-Nur in his prayer. Then the mu'adhdhin called the iqamah. He bowed and prostrated, then sat and recited the tashahhud. Then he stood with the imam and began from where he had reached.
