Offering Salah in the graveyards

A: First: The Prophet (peace be upon him) did not perform any of the obligatory or the supererogatory Salahs in graveyards or in a Masjid (mosque) that has a grave inside; rather, he prohibited this. Secondly: It is confirmed that the Prophet (peace be upon him) offered Salah over a deceased person after burial and said Takbir (saying: "Allahu Akbar [Allah is the Greatest]") four times.
