A Muslim is supposed to make dua (Bismillah Wa- ‘ala Barakatullah) before he or she starts eating. Assuming you are eating in a group is it not permissible for one person to make the dua, and the rest just say: ‘Ameen! and start eating?
Answer
Every person should commence eating by taking the name of Allah and say Bismillah (In the name of Allah)
