Question:
I received an email today from my friend. He informed me that Hazrat Usman (RA) was murdered by son of Hazrat Abu Bakr (RA). Is this true?
 
Answer:
History says that though Hazrat Abubakar (RadiAllahuAnh)s son was invoved but he remained away after Hazrat Usman (RadiAllahuAnh) warned him...So he had no connection with Hazrat Usman (RadiAllahuAnh)s murder.
