Ahmed bin 'Amr bin al-Sarh أحمد بن عمرو بن السرح أبو الطاهر · The Book of the Masjids

"Whoever prays in the Masjid of the Messenger of Allah (ﷺ) (that is good), for I heard the Messenger of Allah (ﷺ) say: ' One prayer offered there is better than a thousand prayers offered elsewhere, except the Masjid of the Ka'bah.'"
