حَدَّثَنِي مُحَمَّدُ بْنُ الْمُثَنَّى ، حَدَّثَنَا يَزِيدُ بْنُ هَارُونَ ، أَخْبَرَنَا عَاصِمُ بْنُ مُحَمَّدِ بْنِ زَيْدٍ ، عَنْ أَبِيهِ ، عَنِ ابْنِ عُمَرَ ، رضى الله عنهما قَالَ قَالَ النَّبِيُّ صلى الله عليه وسلم بِمِنًى " أَتَدْرُونَ أَىُّ يَوْمٍ هَذَا ". قَالُوا اللَّهُ وَرَسُولُهُ أَعْلَمُ. قَالَ " فَإِنَّ هَذَا يَوْمٌ حَرَامٌ، أَفَتَدْرُونَ أَىُّ بَلَدٍ هَذَا ". قَالُوا اللَّهُ وَرَسُولُهُ أَعْلَمُ. قَالَ " بَلَدٌ حَرَامٌ، أَتَدْرُونَ أَىُّ شَهْرٍ هَذَا ". قَالُوا اللَّهُ وَرَسُولُهُ أَعْلَمُ. قَالَ " شَهْرٌ حَرَامٌ ". قَالَ " فَإِنَّ اللَّهَ حَرَّمَ عَلَيْكُمْ دِمَاءَكُمْ وَأَمْوَالَكُمْ وَأَعْرَاضَكُمْ، كَحُرْمَةِ يَوْمِكُمْ هَذَا فِي شَهْرِكُمْ هَذَا فِي بَلَدِكُمْ هَذَا " .
The Prophet (ﷺ) said at Mina, "Do you know what day is today?" They (the people) replied, "Allah and His Apostle know better," He said "Today is 10th of Dhul-Hijja, the sacred (forbidden) day. Do you know what town is this town?" They (the people) replied, "Allah and His Apostle know better." He said, "This is the (forbidden) Sacred town (Mecca a sanctuary)." And do you know which month is this month?" They (the People) replied, "Allah and His Apostle know better." He said, ''This is the Sacred (forbidden) month ." He added, "Allah has made your blood, your properties and your honor Sacred to one another (i.e. Muslims) like the sanctity of this day of yours in this month of yours, in this town of yours." (See Hadith No. 797, Vol. 2.)
