Income tax on Fixed Deposit done by me on name of my mother

If I make a Bank Fixed Deposit in the name of my mother who is a home maker and has no income which I will declare using form 15G.

Then at the time of maturity of the Fixed Deposit is there any possibility that IT department may ask from my mother that from where she got this money to invest in Fixed Deposit and cause any other issues/hurdles to her or me either.

Thanks and Regards
