which have no inhabitants? Then Allah, exalted is He, revealed:
“It is no sin for you to enter uninhabited houses in which there is some benefit for you. And Allah knows what you reveal and what you conceal. (29) Tell the believing men to lower their gaze and guard their private parts. That is purer for them. Surely Allah is All-Aware of what they do. (30)”
His saying, exalted is He, “It is no sin for you to enter uninhabited houses,” means: without seeking permission. “In which there is some benefit for you,” that is, some utility for you.
They differed concerning these houses. Qatadah said: They are inns, houses, and dwellings built for travellers, so that they may take shelter in them and store their belongings there. It is permissible to enter them without seeking permission, and the benefit they provide lies in lodging, storing one’s belongings, and protection from heat and cold.
Ibn Zayd said: They are the houses and shops of merchants in the marketplaces, which people enter for buying and selling; this is the benefit referred to. Ibrahim al-Nakhai said: No permission is required for the shops in the marketplace. When Ibn Sirin came to a shop in the market, he would say, “Peace be upon you. May I enter?” Then he would go in.
Ata said: They are ruined houses, and the benefit is relieving oneself in them by urinating or defecating. It was also said: They are all houses that have no occupants, since seeking permission was prescribed only so that one might not see something private. If this is not feared, one may enter without seeking permission. “And Allah knows what you reveal and what you conceal.”
His saying, exalted is He, “Tell the believing men to lower their gaze,” means: from looking at what it is not lawful to look at. It was said that the word “from” is supplementary; that is, “let them lower their gaze.” It was also said that it retains its meaning, because believers have not been commanded to lower their gaze entirely, for it is not obligatory to avert one’s gaze from what it is lawful to look at. Rather, they have been commanded to lower their gaze from that which it is not lawful to look at.
“And guard their private parts” from what is unlawful. Abu al-Aliyah said: Every occurrence in the Quran of guarding one’s private parts refers to guarding against fornication and what is unlawful, except in this passage, where it means concealing them so that another person’s gaze does not fall upon them. “That,” meaning lowering the gaze and guarding the private parts, “is purer for them,” that is, better and more wholesome for them. “Surely Allah is All-Aware of what they do,” meaning, He knows what they do.
It is narrated from Buraydah that the Messenger of Allah, peace and blessings be upon him, said to Ali: “O Ali, do not follow one glance with another, for the first is excused for you, but the second is not.” (3)
