Sura al-Baqara 2:108

أَمْ تُرِيدُونَ أَن تَسْـَٔلُوا۟ رَسُولَكُمْ كَمَا سُئِلَ مُوسَىٰ مِن قَبْلُ وَمَن يَتَبَدَّلِ ٱلْكُفْرَ بِٱلْإِيمَٰنِ فَقَدْ ضَلَّ سَوَآءَ ٱلسَّبِيلِ

am turīdūna an tasʾalū rasūlakum ka-mā suʾila mūsā min qablu wa-man yatabaddali l-kufra bi-l-īmāni fa-qad ḍalla sawāʾa l-sabīli

Would ye question your Messenger as Moses was questioned of old? but whoever changeth from Faith to Unbelief, Hath strayed without doubt from the even way.

Sura al-Nisāʾ 4:2

وَءَاتُوا۟ ٱلْيَتَٰمَىٰٓ أَمْوَٰلَهُمْ وَلَا تَتَبَدَّلُوا۟ ٱلْخَبِيثَ بِٱلطَّيِّبِ وَلَا تَأْكُلُوٓا۟ أَمْوَٰلَهُمْ إِلَىٰٓ أَمْوَٰلِكُمْ إِنَّهُۥ كَانَ حُوبًا كَبِيرًا

wa-ātū al-yatāma amwālahum wa-lā tatabaddalū l-khabītha bil-ṭayyibi wa-lā takulū amwālahum ila amwālikum innahu kāna ḥūban kabīran

To orphans restore their property (When they reach their age), nor substitute (your) worthless things for (their) good ones; and devour not their substance (by mixing it up) with your own. For this is indeed a great sin.

Sura al-Aḥzāb 33:52

لَّا يَحِلُّ لَكَ ٱلنِّسَآءُ مِنۢ بَعْدُ وَلَآ أَن تَبَدَّلَ بِهِنَّ مِنْ أَزْوَٰجٍ وَلَوْ أَعْجَبَكَ حُسْنُهُنَّ إِلَّا مَا مَلَكَتْ يَمِينُكَ وَكَانَ ٱللَّـهُ عَلَىٰ كُلِّ شَىْءٍ رَّقِيبًا

lā yaḥillu la-ka l-nisāu min baʿdu wa-lā an tabaddala bihinna min azwājin wa-law aʿjabaka ḥusnuhunna illā mā malakat yamīnuka wa-kāna allāhu ʿalā kulli shayʾin rraqīban

It is not lawful for thee (to marry more) women after this, nor to change them for (other) wives, even though their beauty attract thee, except any thy right hand should possess (as handmaidens): and Allah doth watch over all things.
