Direct your prayers and worships towards Allah alone and no one else; Respect Prophets; Avoid idolatry or shirk; Do not build places of worship at graves; Do not take them as a place for prayer or worship either.

In this hadith narrated by 'Aisha, Allah's Messenger (ﷺ) warned against building places of worship at the graves of prophets. This is because it could lead to people worshipping the grave instead. He was afraid that his own grave might be taken as a place for worship if he did not warn against it. This hadith teaches us that we should not build places of worship at graves and should not take them as a place for worship either. We should only direct our prayers and worships towards Allah alone and no one else.
