Musannaf Ibn Abi Shaybah 6388 — The new mosque and the old

Thabit al-Bunani said: Sometimes I would be with Sayyiduna Anas bin Malik (may Allah be pleased with him) when he came to a mosque; he would hear its call to prayer (adhan) and ask: Is this a new mosque? The people would say: Yes. At that he would pass on beyond it, looking for another mosque.
