Jerusalem is the capital of the future Caliphate
Yunus Ibn Maysarah relates that the Prophet Muhammad ﷺ said, هَذَا الأَمْرُ كَائِنٌ بَعْدِي بِالْمَدِينَةِ ، ثُمَّ بِالشَّامِ ، ثُمَّ بِالْجَزِيرَةِ ، ثُمَّ بِالْعِرَاقِ ، ثُمَّ بِالْمَدِينَةِ ، ثُمَّ بِبَيْتِ الْمَقْدِسِ ، فَإِذَا كَانَ بِبَيْتِ الْمَقْدِسِ فَثَمَّ عُقْرُ دَارِهَا ، وَلَنْ يُخْرِجَهَا قَوْمٌ فَتَعُودَ إِلَيْهِمْ أَبَدًا “This matter (the Caliphate) will be after me in Madinah, then in Al-Sham, then in the peninsula, then in Iraq, then in the City (Constantinople), then in Bait ul-Maqdis (Jerusalem). If it is in Bait ul-Maqdis, its home country is there, and no people will be able to remove it, so it will return to them forever.” [Ibn Asakir, 368]
