‘Abdullāh ibn Mas‘ūd (may Allah be pleased with him) reported that the Prophet (may Allah's peace and blessings be upon him) said: "Among the most wicked people are those who will be alive when the Hour comes, and those who take the graves as places of worship."
The Prophet (may Allah's peace and blessings be upon him) tells us that those who will be alive and witness the advent of the Hour are the most evil of people, and that this includes as well those who pray at and towards the graves and build domes upon them. This is a warning from the Prophet (may Allah's peace and blessings be upon him) to his Ummah against following the practices of those evil people with regard to the graves of their prophets and righteous people.
