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 Saʿ and Mudd (i.e. units of measuring)."
أَنَّهُ سَمِعَ أَنَسَ بْنَ مَالِكٍ ؓ يَقُولُ خَرَجْتُ مَعَ رَسُولِ اللَّهِ ﷺ إِلَى خَيْبَرَ أَخْدُمُهُ فَلَمَّا قَدِمَ النَّبِيُّ ﷺ 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
