The Prophet ﷺ said: The place of assembly of the Muslims at the time of the war will be in al-Ghutah near a city called Damascus, one of the best cities in Syria.
أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ إِنَّ فُسْطَاطَ الْمُسْلِمِينَ يَوْمَ الْمَلْحَمَةِ بِالْغُوطَةِ إِلَى جَانِبِ مَدِينَةٍ يُقَالُ لَهَا دِمَشْقُ مِنْ خَيْرِ مَدَائِنِ الشَّامِ
