"The Messenger of Allah said on the day of the conquest of Makkah: 'Allah, the Might and Sublime, has made this land sacred, and it was not permissible to fight therein for anyone before me. It was permitted for me for a few hours of a day, and it is sacred by the decree of Allah, the Might and Sublime." (Using translation from Nasāʾī 2875)
قَالَ رَسُولُ اللهِ ﷺ يَوْمَ فَتْحِ مَكَّةَ «إِنَّ هَذَا الْبَلَدَ حَرَمٌ حَرَّمَهُ اللهُ لَمْ يَحِلَّ فِيهِ الْقِتَالُ لِأَحَدٍ قَبْلِي وَأُحِلَّ لِي سَاعَةً مِنْ نَهَارٍ فَهُوَ حَرَامٌ بِحُرْمَةِ اللهِ»
