اِنَّ اَوَّلَ بَیْتٍ وُّضِعَ لِلنَّاسِ لَلَّذِیْ بِبَكَّةَ مُبٰرَكًا وَّهُدًی لِّلْعٰلَمِیْنَ ۟

Inna awwala Baitinw wudi'a linnaasi lallazee bi Bakkata mubaarakanw wa hudal lil 'aalameen

“The first House (of worship) appointed for men was that at Bakka: Full of blessing and of guidance for all kinds of beings:”
