Narrated Abu Sa'id al-Khudri (RA):

The Prophet (ﷺ) said: "No (religious) journey is to be undertaken except to (pray in) the three mosques: The Sacred Mosque (Makkah), the Aqsa Mosque (Jerusalem), and this Mosque of mine (al-Madinah)." [Agreed upon, and the wording is al-Bukhari's].

وَعَنْ أَبِي سَعِيدٍ اَلْخُدْرِيِّ ‏- رضى الله عنه ‏- عَنْ اَلنَّبِيِّ ‏- صلى الله عليه وسلم ‏-قَالَ: {

لَا تُشَدُّ اَلرِّحَالُ إِلَّا إِلَى ثَلَاثَةِ مَسَاجِدَ: مَسْجِد اَلْحَرَامِ, وَمَسْجِدِ اَلْأَقْصَى, وَمَسْجِدِي

} مُتَّفَقٌ عَلَيْهِ, وَاللَّفْظُ لِلْبُخَارِيِّ [1]‏ .‏
