Dude, will you quit applying ahadith meant for the KUFAR on MUslims please !! here read this ..
Some people quote a Hadith of the Prophet Mohammad (صلى الله عليه و آله وسلم) in which he ordered Ali(رضئ اللہ تعالی عنہ) to "go and destroy every over-sized grave." This Hadith is in the Sahihayn, Sunan, and Musnad with various wordings.
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.
The above Hadith is misinterpreted by certain sects. There is no exception to this Hadith; the sects have misinterpreted the entire Quran and Ahadith books. We have cautioned Muslims, time and again, in our articles that one should learn Islam in the company of an authentic Shaikh of Ihsan. We should not read Quran and Ahadith independently and deduce rules based on our limited understanding. If we do that, there is a strong possibility that we misunderstand the meanings and go astray.
Imam Sufyan al-Thawri rightly said: "(the wordings of) this Hadith may misguide people except those who possess (Sahi) understanding (of Islam)."
Therefore, the correct understanding of the Hadith is, Prophet (صلى الله عليه و آله وسلم) asked Ali (رضئ اللہ تعالی عنہ) to destroy all graves of non-believers (pagans) which were high on the ground. This correct understanding is based on the following Hadith of Prophet Mohammad(صلى الله عليه و آله وسلم).
