125وَإِذْ جَعَلْنَا ٱلْبَيْتَ مَثَابَةً لِّلنَّاسِ وَأَمْنًا وَٱتَّخِذُوا۟ مِن مَّقَامِ إِبْرَٰهِـۧمَ مُصَلًّى ۖ وَعَهِدْنَآ إِلَىٰٓ إِبْرَٰهِـۧمَ وَإِسْمَـٰعِيلَ أَن طَهِّرَا بَيْتِىَ لِلطَّآئِفِينَ وَٱلْعَـٰكِفِينَ وَٱلرُّكَّعِ ٱلسُّجُودِ
[125] And remember that We made this House (the Ka'bah) the centre nd sanctuary for mankind and enjoined the people to dedicate to worship the place where Abraham used to stand for prayer, and We urged Abraham and Ismail to keep My House pure for those who would go round it and those who would retire to it for devotion and prayer and for those who would bow down and prostrate themselves there in worhsip.126
126The purification of the House was not only to be from rubbish but also from all kinds of false worship so that the name of Allah alone should be glorified in it. The real purification of Allah's House is that no other name than His should be mentioned in it. For the worship of anyone else or the invoking of any other name for help really polluted the House. This verse charges, in a subtle manner, the Quraish with the crime of keeping idols in the Ka`bah and worshipping them instead of Allah. It implies that these idolaters who were proud of being the heirs of Abraham and Ismail were not discharging the obligations of that heritage. Hence they, like the Israelites, have forfeited all rights to the promise of Allah made to Abraham.
