Sura al-Nisāʾ 4:6

وَٱبْتَلُوا۟ ٱلْيَتَٰمَىٰ حَتَّىٰٓ إِذَا بَلَغُوا۟ ٱلنِّكَاحَ فَإِنْ ءَانَسْتُم مِّنْهُمْ رُشْدًا فَٱدْفَعُوٓا۟ إِلَيْهِمْ أَمْوَٰلَهُمْ وَلَا تَأْكُلُوهَآ إِسْرَافًا وَبِدَارًا أَن يَكْبَرُوا۟ وَمَن كَانَ غَنِيًّا فَلْيَسْتَعْفِفْ وَمَن كَانَ فَقِيرًا فَلْيَأْكُلْ بِٱلْمَعْرُوفِ فَإِذَا دَفَعْتُمْ إِلَيْهِمْ أَمْوَٰلَهُمْ فَأَشْهِدُوا۟ عَلَيْهِمْ وَكَفَىٰ بِٱللَّـهِ حَسِيبًا

wa-ibtalū l-yatāmā ḥatta idhā balaghū l-nikāḥa fa-in ānastum minhum rushdan fa-idfaʿū ilayhim amwālahum wa-lā takulūhā isrāfan wa-bidāran an yakbarū wa-man kāna ghaniyyan fa-l-yastaʿfif wa-man kāna faqīran fa-l-yāʾkul bil-maʿrūfi fa-idhā dafaʿtum ilayhim amwālahum fa-ashhidū ʿalayhim wa-kafā billāhi ḥasīban

Make trial of orphans until they reach the age of marriage; if then ye find sound judgment in them, release their property to them; but consume it not wastefully, nor in haste against their growing up. If the guardian is well-off, Let him claim no remuneration, but if he is poor, let him have for himself what is just and reasonable. When ye release their property to them, take witnesses in their presence: But all-sufficient is Allah in taking account.

Sura al-Nūr 24:27

يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوا۟ لَا تَدْخُلُوا۟ بُيُوتًا غَيْرَ بُيُوتِكُمْ حَتَّىٰ تَسْتَأْنِسُوا۟ وَتُسَلِّمُوا۟ عَلَىٰٓ أَهْلِهَا ذَٰلِكُمْ خَيْرٌ لَّكُمْ لَعَلَّكُمْ تَذَكَّرُونَ

yā-ayyuhā lladhīna āmanū lā tadkhulū buyūtan ghayra buyūtikum ḥattā tastaʾnisū wa-tusallimū ʿala ahlihā dhālikum khayrun la-kum la-ʿallakum tadhakkarūna

O ye who believe! enter not houses other than your own, until ye have asked permission and saluted those in them: that is best for you, in order that ye may heed (what is seemly).
