Hadith 6278
وَعَنْ رَجُلٍ مِنَ الصَّحَابَةِ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ: سَتُفْتَحُ الشَّامُ فإِذا خُيِّرْتم المنازلَ فِيهَا فَعَلَيْكُم بِمَدِينَة يُقَال لَهُ دِمَشْقُ فَإِنَّهَا مَعْقِلُ الْمُسْلِمِينَ مِنَ الْمَلَاحِمِ وَفُسْطَاطُهَا مِنْهَا أَرْضٌ يُقَالُ لَهَا: الْغُوطَةُ . رَوَاهُمَا أَحْمَدُ
One of the Companions reported God's messenger as saying, "Syria will be conquered, and when you are given your choice of places in which to settle go on a city called Damascus, for it will be the fortress of the Muslims to protect them in the wars during which it will be a place of assembly. In its neighbourhood there is some land called al-Ghuta." Ahmad transmitted the two traditions.
