Mishkat al-Masabih
Abu Huraira reported God’s Messenger as saying, “The space between the East and the West is a qibla.” Tirmidhi transmitted it.
عَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «مَا بَيْنَ الْمَشْرِقِ وَالْمَغْرِبِ قِبْلَةٌ» . رَوَاهُ التِّرْمِذِيُّ
