"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.'" (Using translation from Nasāʾī 691)   

أَنَّ مَيْمُونَةَ زَوْجَ النَّبِيِّ ﷺ قَالَتْ صَلِّ فِي مَسْجِدِ الرَّسُولِ ﷺ فَإِنِّي سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ «صَلَاةٌ فِيهِ أَفْضَلُ مِنْ أَلْفِ صَلَاةٍ فِيمَا سِوَاهُ مِنَ الْمَسَاجِدِ إِلَّا مَسْجِدَ الْكَعْبَةِ»
