Narrated Anas bin Malik:I went along with the Prophet (ﷺ) to Khaibar so as to serve him. (Later on) when the Prophet (ﷺ) returned he, on seeing the Uhud mountain, said, "This is a mountain that loves us and is loved by us." Then he pointed to Medina with his hand saying, "O Allah! I make the area which is in between Medina's two mountains a sanctuary, as Abraham made Mecca a sanctuary. O Allah! Bless us in our Sa` and Mudd (i.e. units of measuring)."
حَدَّثَنَا عَبْدُ الْعَزِيزِ بْنُ عَبْدِ اللَّهِ، حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ، عَنْ عَمْرِو بْنِ أَبِي عَمْرٍو، مَوْلَى الْمُطَّلِبِ بْنِ حَنْطَبٍ، أَنَّهُ سَمِعَ أَنَسَ بْنَ مَالِكٍ ـ رضى الله عنه ـ يَقُولُ خَرَجْتُ مَعَ رَسُولِ اللَّهِ صلى الله عليه وسلم إِلَى خَيْبَرَ أَخْدُمُهُ، فَلَمَّا قَدِمَ النَّبِيُّ صلى الله عليه وسلم رَاجِعًا، وَبَدَا لَهُ أُحُدٌ قَالَ " هَذَا جَبَلٌ يُحِبُّنَا وَنُحِبُّهُ ". ثُمَّ أَشَارَ بِيَدِهِ إِلَى الْمَدِينَةِ قَالَ اللَّهُمَّ إِنِّي أُحَرِّمُ مَا بَيْنَ لاَبَتَيْهَا كَتَحْرِيمِ إِبْرَاهِيمَ مَكَّةَ " اللَّهُمَّ بَارِكْ لَنَا فِي صَاعِنَا وَمُدِّنَا ".
