Surah Al-Imran, ayah 96

3:96

إِنَّ أَوَّلَ بَيۡتٖ وُضِعَ لِلنَّاسِ لَلَّذِي بِبَكَّةَ مُبَارَكٗا وَهُدٗى لِّلۡعَٰلَمِينَ ٩٦

Inna awwala baytin wudi'a lin-nāsi lalladhī bibakkata mubārakan wahudal lil-'ālamīn

Indeed, the first House [of worship] established for mankind was that at Bakkah [i.e., Makkah] - blessed and a guidance for the worlds.
