Advising a sinner

Q 2: What is the ruling on people who blaspheme religion, even if they are first-degree relatives (father, brother, and so on)? What is (Part No. 12; Page No. 350) the legal ruling on graves that are in Masjids (Mosques) such as, Ibrahim Al-Dusuqy, Al-Sayyid Al-Badawy, Al-Husayn, and so on? What is the ruling on Masjids that have graves inside them? Does the Hadith of the Messenger (peace be upon him), “May Allah curse the Jews and the Christians, for they have taken the graves of their Prophets as places of worship” apply to them?

A: First, blaspheming the religion of Islam is Kufr (disbelief). Whoever hears anyone doing so, should forbid this Munkar (that which is unacceptable or disapproved of by Islamic law and Muslims of sound intellect) and advise the person who commits this sin to repent so that he may accept the advice and stop committing this Munkar. Moreover, if they are relatives, the person has to make sure that they do not commit this Munkar. Second, it is not permissible to build Masjids on graves or to bury the dead there. It is also not permissible to offer Salah in these Masjids.
