عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ رَضِيَ اللَّهُ عَنْهُ عَنِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ قَالَ: ((لَيُحَجَّنَّ الْبَيْتُ وَلَيُعْتَمَرَنَّ بَعْدَ يَأْجُوجَ وَمَأْجُوجَ))
It is narrated from Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him and his family) said: Even after the emergence of Gog and Magog, Hajj and Umrah of the House of Allah will be performed.
