﴿ فِى بُيُوتٍ أَذِنَ ٱللَّهُ أَن تُرْفَعَ وَيُذْكَرَ فِيهَا ٱسْمُهُۥ يُسَبِّحُ لَهُۥ فِيهَا بِٱلْغُدُوِّ وَٱلْءَاصَالِ ﴾

“IN THE HOUSES [of worship] which God has allowed to be raised so that His name be remembered in them, there [are such as] extol His limitless glory at morn and evening –”

((This lamp is found) in houses) these lamps are hung in houses (which Allah hath allowed) which Allah has commanded (to be exalted) to be built; the reference here is to mosques (and that His Name) His divine Oneness (shall be remembered therein) in the mosques. (Therein) in the mosques (do offer praise to Him) pray to Him (at morn) the Fajr prayer (and evening) the prayers of Zuhr, 'Asr, Maghrib and 'Isha'.
