Respect for Allah's commands, Avoiding shirk or idolatry

According to the hadith narrated by Abdullah ibn Abbas, the Prophet Muhammad cursed those who visit graves, build mosques over them and erect lamps there. This hadith teaches us that visiting graves is forbidden in Islam as it can lead to shirk or idolatry. It also teaches us that building a mosque on top of a grave or lighting a lamp near it is also forbidden as these are signs of reverence which should only be given to Allah alone. We should remember this teaching and not engage in any activities which may lead us astray from the path of righteousness.
