Many of great Muslim Scholars, Like Moulana Moudadi, Moulana Shaukat Ali Thanvi, Moulana shafiullah, Moulana Nadvi, so on. Always said to Muslims not to say anything bad to Ram, Krishna, Gautam Budh and others because they were one of the good people, good human being. As Allah said in the Quran I sent every nation, best people, messengers, and guides to direct and show people right path. May they were among one of them. Muslim not believe that Prophet Mohammed (PBUH) OR any other prophet or person as GOD or Deity. We believe that they were just mere human being like us and servant of ALLAH. Allah had given them a task to give a message to people they did the same. Nothing more.
