Musannaf Ibn Abi Shayba 3:5347

Ibn ‘Ulayyah narrated to us, from Ayyub, who said: I saw ‘Abdullah ibn Abi Mulaykah leading the people in prayer during Ramadan behind the Maqam (Station of Ibrahim), along with those who prayed behind him, while the people were still in the rest of the mosque, between those circumambulating the House and those praying.
