She came to Maimuna. the wife of Allah's Apostle ﷺ. and after greeting her she informed her about it, whereupon she said: Stay here. and eat the provision (which you had made) and observe prayer In the mosque of the Messenger ﷺ. for I heard Messenger of Allah ﷺ say: Prayer In it is better than a thousand prayers observed in other mosques except the mosque of the Ka'ba. (Using translation from Muslim 1396)
لَئِنْ شَفَانِي اللهُ لَأَخْرُجَنَّ فَلَأُصَلِّيَنَّ فِي بَيْتِ الْمَقْدِسِ فَبَرِأَتْ فَتَجَهَّزَتْ تُرِيدُ الْخُرُوجَ فَجَاءَتْ مَيْمُونَةَ زَوْجَ النَّبِيِّ ﷺ تُسَلِّمُ عَلَيْهَا فَأَخْبَرَتْهَا ذَلِكَ فَقَالَتْ اجْلِسِي فَكُلِي مَا صَنَعْتُ وَصَلِّي فِي مَسْجِدِ الرَّسُولِ ﷺ فَإِنِّي سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ صَلَاةٌ فِيهِ أَفْضَلُ مِنْ أَلْفِ صَلَاةٍ فِيمَا سِوَاهُ مِنَ الْمَسَاجِدِ إِلَّا مَسْجِدَ الْكَعْبَةِ
