…Does that amount becomes halal for me and if i give sadaqa from that amount or from my belongings then is it counted as sadaqa?

The money he gives to you is not 100% haram. Therefore, whatever he gives you it becomes halal to you and you can also give sadaqa out of that.

My husband works in a bank, so his earning is haram. So whatever he buys for me does those things or clothes or jewellery becomes halal for me? If not then what is to be done with those things, or whatever money he gives me?…
