Sahih al-Bukhari #1190Sahih
السَّلَامُ عَلَيْكَ يَا رَسُولَ اللَّهِ وَرَحْمَةُ اللَّهِ وَبَرَكَاتُهُ. السَّلَامُ عَلَيْكَ يَا نَبِيَّ اللَّهِ. أَشْهَدُ أَنَّكَ قَدْ بَلَّغْتَ الرِّسَالَةَ وَأَدَّيْتَ الْأَمَانَةَ وَنَصَحْتَ الْأُمَّةَ وَجَاهَدْتَ فِي اللَّهِ حَقَّ جِهَادِهِ
The Prophet (peace be upon him) said: 'Do not undertake a journey except to three mosques: Masjid al-Haram, this mosque of mine (Masjid an-Nabawi), and Masjid al-Aqsa.' And he said: 'One prayer in my mosque is better than one thousand prayers in any other mosque except Masjid al-Haram.'
