Musannaf Ibn Abi Shayba 3:3956

Abu Bakr narrated to us, he said: Waki’ narrated to us, from Ali ibn Mubarak, from Yahya ibn Abi Kathir, from Abu Salamah, from Aisha, that the Prophet (peace and blessings of Allah be upon him) used to pray the two rak'ahs at the time of the iqamah, between the adhan and the iqamah.
