Al-Baqarah 2:125 واذ جعلنا البيت مثابة للناس وامنا واتخذوا من مقام ابراهيم مصلى وعهدنا الى ابراهيم واسماعيل ان طهرا بيتي للطايفين والعاكفين والركع السجود ١٢٥

And (remember) when We made the House (the Ka‘bah at Makkah) a place of resort for mankind and a place of safety. And take you (people) the Maqâm (place) of Ibrâhîm (Abraham) [or the stone on which Ibrâhîm (Abraham) عليه السلام stood while he was building the Ka‘bah] as a place of prayer (for some of your prayers, e.g. two Rak‘at after the Tawâf of the Ka‘bahat Makkah), and We commanded Ibrâhîm (Abraham) and Ismâ‘îl (Ishmael) that they should purify My House (the Ka‘bah at Makkah) for those who are circumambulating it, or staying (I‘tikâf), or bowing or prostrating themselves (there, in prayer).
