﴿ إِنَّمَا يَعْمُرُ مَسَٰجِدَ ٱللَّهِ مَنْ ءَامَنَ بِٱللَّهِ وَٱلْيَوْمِ ٱلْءَاخِرِ وَأَقَامَ ٱلصَّلَوٰةَ وَءَاتَى ٱلزَّكَوٰةَ وَلَمْ يَخْشَ إِلَّا ٱللَّهَ ۖ فَعَسَىٰٓ أُو۟لَٰٓئِكَ أَن يَكُونُوا۟ مِنَ ٱلْمُهْتَدِينَ ﴾

“Only he should visit or tend God's houses of worship who believes in God and the Last Day, and is constant in prayer, and spends in charity, and stands in awe of none but God: for [only such as] these may hope to be among the right-guided!”

At the time when the Quran was revealed, the position in Arabia was that the Muslims had gathered round the Prophet Muhammad and the polytheists around the Ka‘bah. Till that time the histories of glories which we are now acquainted with had not yet become attached to the name of the Prophet Muhammad. He appeared to the people like an ordinary man. On the other hand, the Sacred Mosque of Makkah, because of the thousands of years of history attached to it, appeared to them a symbol of greatness and holiness. The polytheists saw themselves as being servants and retainers of the holiest shrine. On the contrary, when they saw the Muslims, they thought of them, under the circumstances prevailing at that time, as a group of people gathered around a madman.
