Is it permissible for me to accept wealth that was set aside for me by my non-Muslim father as

Yes, this is permissible for you, unless you know that the specific wealth that was set aside as a bequest for you came into your father's possession through a means not sanctioned by Sacred Law, such as usurious gain (riba) or other unlawful [h: transactions]. If this were the case, it would be unlawful for you to accept it.

(Translated by Sidi Hamza Karamali)

السؤال  : هل يجوز لي أن أقبل مالا عينه لى والدي الكافر بطريق الوصية ؟

 الجواب : نعم يجوز لك ذلك إلا إن علمتَ أن عين المال الموصى لك به دخل ملكَ والدك بغير طريق شرعي كعقد ربا ونحوه من المحرمات فيحرم عليك حينئذ قبوله .
