Al-Baqi

Al-Baqi is the first and oldest Islamic cemetery of Madina where four Shi’a Imams (a) and many other noble ones among the Sahaba and the Tabi’un are buried. Some structures were built over the graves of these Imams (a) as well as other figures which were known as Buq’as of Baqi’. These buq’as were destroyed by Wahhabis in an incident called the Demolition of al-Baqi’.
