Is it bid’ah to make dua before we eat “allahumma barik lama fima razaqtana wa qina adzabannar” or sunnah? Is it more recommended to make that dua before we eat or just bismillah or bismillahirahmanirrahim

Ustadh AbdulAziz al-Haqqan

Don't link du'as to certain activities if the Prophet ﷺ didn't do so, so that it doesn't become a bid'ah.
