What was the Prophet Muhammad (saw) afraid of regarding his grave?
 Narrated `Urwa bin Az-Zubair:                     `Aisha said, "The Prophet said during his fatal illness, "Allah cursed the Jews for they took the graves of their prophets as places for worship." `Aisha added, "Had it not been for that (statement of the Prophet ) his grave would have been made conspicuous. But he was afraid that it might be taken as a place for worship."
