"I said: 'O Messenger of Allah! Which mosque was built first?' He said: 'Al-Masjid Al-Haram (in Makkah).' I said: 'Then which?' He said: 'then Al-Masjid Al-Aqsa (in Jerusalem).' I said: 'How many years between them?' He said: 'Forty years, but the whole earth is a mosque for you, so pray wherever you are when the time for prayer comes.'"  

قُلْتُ يَا رَسُولَ اللَّهِ أَىُّ مَسْجِدٍ وُضِعَ أَوَّلُ قَالَ الْمَسْجِدُ الْحَرَامُ قَالَ قُلْتُ ثُمَّ أَىٌّ قَالَ ثُمَّ الْمَسْجِدُ الأَقْصَى قُلْتُ كَمْ بَيْنَهُمَا قَالَ أَرْبَعُونَ عَامًا ثُمَّ الأَرْضُ لَكَ مُصَلًّى فَصَلِّ حَيْثُ مَا أَدْرَكَتْكَ الصَّلاَةُ
