The virtue of the Three Masajid
وَحَدَّثَنَاهُ أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا عَبْدُ الأَعْلَى، عَنْ مَعْمَرٍ، عَنِ الزُّهْرِيِّ، بِهَذَا الإِسْنَادِ غَيْرَ أَنَّهُ قَالَ " تُشَدُّ الرِّحَالُ إِلَى ثَلاَثَةِ مَسَاجِدَ " .
This hadith has been narrated on the authority of Zuhri (but with this change of words) that he (Allah's Messenger) said:" Undertake journey to three mosques."
