Narrated Ibn 'Umar:

At Mina, the Prophet ﷺ said, "Do you know what is the day today?" The people replied, "Allah and His Apostle know it better." He said, "It is the forbidden (sacred) day. And do you know what town is this?" They replied, "Allah and His Apostle know it better." He said, "This is the forbidden (Sacred) town (Mecca). And do you know which month is this?" The people replied, "Allah and His Apostle know it better." He said, "This is the forbidden (sacred) month." The Prophet added, "No doubt, Allah made your blood, your properties, and your honor sacred to one another like the sanctity of this day of yours in this month of yours in this town of yours." Narrated Ibn 'Umar: On the Day of Nahr (10th of Dhul-Hijja), the Prophet stood in between the Jamrat during his Hajj which he performed (as in the previous Hadith) and said, "This is the greatest Day (i.e. 10th of Dhul-Hijjah)." The Prophet started saying repeatedly, "O Allah! Be Witness (I have conveyed Your Message)." He then bade the people farewell. The people said, "This is Hajjat-al-Wada)."

حَدَّثَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، حَدَّثَنَا يَزِيدُ بْنُ هَارُونَ، أَخْبَرَنَا عَاصِمُ بْنُ مُحَمَّدِ بْنِ زَيْدٍ، عَنْ أَبِيهِ، عَنِ ابْنِ عُمَرَ ـ رضى الله عنهما ـ قَالَ قَالَ النَّبِيُّ ﷺ بِمِنًى " أَتَدْرُونَ أَىُّ يَوْمٍ هَذَا ". قَالُوا اللَّهُ وَرَسُولُهُ أَعْلَمُ. فَقَالَ " فَإِنَّ هَذَا يَوْمٌ حَرَامٌ، أَفَتَدْرُونَ أَىُّ بَلَدٍ هَذَا ". قَالُوا اللَّهُ وَرَسُولُهُ أَعْلَمُ. قَالَ " بَلَدٌ حَرَامٌ، أَفَتَدْرُونَ أَىُّ شَهْرٍ هَذَا ". قَالُوا اللَّهُ وَرَسُولُهُ أَعْلَمُ. قَالَ " شَهْرٌ حَرَامٌ ـ قَالَ ـ فَإِنَّ اللَّهَ حَرَّمَ عَلَيْكُمْ دِمَاءَكُمْ وَأَمْوَالَكُمْ وَأَعْرَاضَكُمْ، كَحُرْمَةِ يَوْمِكُمْ هَذَا، فِي شَهْرِكُمْ هَذَا، فِي بَلَدِكُمْ هَذَا ". وَقَالَ هِشَامُ بْنُ الْغَازِ أَخْبَرَنِي نَافِعٌ عَنِ ابْنِ عُمَرَ ـ رضى الله عنهما ـ وَقَفَ النَّبِيُّ ﷺ يَوْمَ النَّحْرِ بَيْنَ الْجَمَرَاتِ فِي الْحَجَّةِ الَّتِي حَجَّ بِهَذَا، وَقَالَ " هَذَا يَوْمُ الْحَجِّ الأَكْبَرِ "، فَطَفِقَ النَّبِيُّ ﷺ يَقُولُ " اللَّهُمَّ اشْهَدْ ". وَوَدَّعَ النَّاسَ. فَقَالُوا هَذِهِ حَجَّةُ الْوَدَاعِ.
