anwar4ever, You are certainly very "brave" man as you are trying to convince Muslims not follow the instruction of our beloved Prophet Muhammad pbuh as mentioned in following Sahih Muslim hadiths:
Thumama b. Shafayy reported: When we were with Fadala b. 'Ubaid in the country of the Romans at a place (known as) Rudis, a friend of ours died. Fadala b. 'Ubaid ordered to prepare a grave for him and then it was levelled; and then he said: I heard the Messenger of Allah (may peace be upon him) commanding ((us)) to level the grave. (Sahih Muslim; Book #004, Hadith #2114)
abu'l-Hayyaj al-asadi told that 'ali (b. abu Talib) said to him: Should I not send you on the same mission as allah's Messenger (may peace be upon him) sent me? Do not leave an image without obliterating it, or a high grave without levelling it. This hadith has been reported by Habib with the same chain of transmitters and he said: (Do not leave) a picture without obliterating it. (Sahih Muslim; Book #004, Hadith #2115)
You might be able to get reward in this world for your "bravery" but this world is very limited and we must be more interested in the hereafter than this fragile world.
What you are trying to say that since our beloved Prophet Muhammad pbuh grave is intact hence we should ignore the instruction of our beloved Prophet Muhammad pbuh as mentioned in above Sahih Muslim hadiths and start constructing the Mazars of saints so that Muslims can continue their Shirkia acts? what a "brave" man you are!!
Do you know why our beloved Prophet Muhammad pbuh were not buried in open place and were actually buried in the "hujra" (home) of Ummat-ul-Momineen Aisha (RA). The only reason was to avoid the possibility of grave worshiping.
