(4) باب فَضْلِ الصَّلاَةِ فِي الْمَسْجِدِ الْحَرَامِ
It was narrated from Ibn 'Abbas that Maimunah the wife of the Prophet (ﷺ) said:
"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.'"
