السَّلامُ عَلَـيْكُمْ أَهْلَ الدِّيارِ مِنَ المؤْمِنيـنَ وَالْمُسْلِمين، وَإِنّا إِنْ شاءَ اللهُ بِكُـمْ لاحِقـون، نَسْـاَلُ اللهَ لنـا وَلَكُـمْ العـافِيَة

Peace be upon you, people of this abode, from among the believers and those who are Muslims, and we, by the Will of Allah, shall be joining you.
