Surah An-Nur, ayah 29

لَّيۡسَ عَلَيۡكُمۡ جُنَاحٌ أَن تَدۡخُلُواْ بُيُوتًا غَيۡرَ مَسۡكُونَةٖ فِيهَا مَتَٰعٞ لَّكُمۡۚ وَٱللَّهُ يَعۡلَمُ مَا تُبۡدُونَ وَمَا تَكۡتُمُونَ ٢٩

Llaysa 'alaykum junāhun an tadkhulū buyūtan ghayra maskūnatin fīhā matā'ul lakum wallāhu ya'lamu mā tubdūna wamā taktumūn

There is no blame upon you for entering houses not inhabited in which there is convenience⁹⁸⁷ for you. And Allāh knows what you reveal and what you conceal.
