NASAI 691:
from Ibrāhīm b. ʿAbdullāh b. Maʿbad b. ʿAbbās —
"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.'"
النسائي ٦٩١:
عن ابراهيم بن عبد الله بن معبد بن عباس —
أَنَّ مَيْمُونَةَ زَوْجَ النَّبِيِّ ﷺ قَالَتْ مَنْ صَلَّى فِي مَسْجِدِ رَسُولِ اللَّهِ ﷺ فَإِنِّي سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ الصَّلاَةُ فِيهِ أَفْضَلُ مِنْ أَلْفِ صَلاَةٍ فِيمَا سِوَاهُ إِلاَّ مَسْجِدَ الْكَعْبَةِ
