وَعَنِ اِبْنِ اَلزُّبَيْرِ رَضِيَ اَللَّهُ عَنْهُمَا قَالَ: قَالَ رَسُولُ اَللَّهِ – صلى الله عليه وسلم -{ صَلَاةٌ فِي مَسْجِدِي هَذَا أَفْضَلُ مِنْ أَلْفِ صَلَاةٍ فِيمَا سِوَاهُ إِلَّا اَلْمَسْجِدَ اَلْحَرَامَ , وَصَلَاةٌ فِي اَلْمَسْجِدِ اَلْحَرَامِ أَفْضَلُ مِنْ صَلَاةٍ فِي مَسْجِدِي بِمِائَةِ صَلَاةٍ } رَوَاهُ أَحْمَدُ, وَصَحَّحَهُ اِبْنُ حِبَّانَ 1 . 1 – صحيح. رواه أحمد ( 4 / 5 )، وابن حبان ( 1620 ).

Ibn Az-Zubair (RAA) narrated that the Messenger of Allah (صلى الله عليه وسلم) said: “Offering prayer in my mosque (in Madinah) is better than one thousand prayers elsewhere, save for those offered prayer in al-Masjid al-Haram (in Makkah). And prayer offered in al-Masjid al-Haram is better than prayer offered in my mosque by one hundred prayers.” Related by Ahmad and Ibn Hibban graded it as Sahih.
