“(Lit is such a light) in houses, which Allah hath permitted to be raised to honour; for the celebration, in them of His name: in them is He glorified in the mornings and in the evenings, (again and again)― By men whom neither traffic nor merchandise can divert from the Remembrance of Allah nor from regular Prayer, nor from the practice of regular Charity: their (only) fear is for the Day when hearts and eyes will be transformed (in a world wholly new)― That Allah may reward them according to the best of their deeds, and add even more for them out of His Grace: for Allah doth provide for those whom He will, without measure .”(an-Nur, 24/36-38)
The interpreters say that what is meant by the word “houses” in the verse are mosques and houses of believers. (see Mawardi, Shawkani, the interpretation of the relevant verse) According to Abu Hayyan, the word “houses” in the verse includes all of the houses where people perform prayers and have religious talks. (see Abu Hayyan, Alusi, the interpretation of the relevant verse). According to Ikrima, these houses are all of the mosques and houses where the light of belief is lit. All of the places where people perform prayers and have religious and scholarly talks in the light of lamps at night are included in the scope of this word. (see Ibn Atiyya, the interpretation of the relevant verse). On the one hand, the electric light that illuminates the houses; on the other hand, the light of belief that enlightens the hearts...
On the other hand, it is remarkable that the word “house” is used instead of the word “mosque” in the verse.
“We inspired Moses and his brother with this message: "Provide dwellings for your People in Egypt, make your dwellings into places of worship, and establish regular prayers: and give Glad Tidings to those who believe.”(Yunus, 10/87)
As it is indicated in the verse above, it is more appropriate to conclude that it is necessary for the houses of the believers to resemble mosques where Allah is mentioned and where people who glorify Him in the morning and in the evening are present. This shows that what fits an ideal Muslim family is to mention Allah in the morning and in the evening, to glorify Him, to read His book and to try to learn the knowledge that will make them attain His consent and it also shows that this duty is mainly incumbent on the head of the family.
It is also remarkable that the verse does not propose a model out of life and that it does not exclude trade and business. Ibn Abbas states the following:
“These people about whom Allah gives His luminous light as an example may be those who do business the most and who buy and sell things the most but these activities do not prevent them from mentioning Allah.” (Mustadrak, 2:432, no. 3506)
The following is also reported from Ibn Abbas about the verses above:
“Mosques are Allah’s houses on earth; they emit light for the dwellers of the sky like the stars that emit light for the dwellers of the earth.”(see Razi, Tafsir, the relevant verses)
The word mosque indicates all places, whether closed or open, in other words, it indicates all parts of the world. As a matter of fact, the following hadith is the best evidence for it:
"... The earth has been made for me a place for praying (mosque) and a clean thing (to perform tayammum)." (Bukhari, Tayammum, 1; Salat, 56; Muslim, Masajid, 3, 4, 5)
“Do not abandon performing prayers at home; know that it is more virtuous for a person to perform the prayers except the fard prayers at home.”
"Do not make your houses cemeteries (Perform some prayers at home). Satan definitely escapes from a house where the chapter of al-Baqara is read."(see Muslim, Salatu'l-Musafirin, 212-213; Tirmidhi, Fadail, 2)
The importance of transforming houses into mosques and glorifying Allah there is indicated in the hadiths above.
It is necessary not to doubt that the houses in which Allah’s perfect attributes, the creed of the hereafter, the prophethood of Hz. Muhammad (pbuh), the heavenly identity of the Quran and the high ethics advised by Islam are mentioned will be like luminous rays and light-emitting candles all the time and especially in this age, when mischief has increased and worldly desires are pursued.
