Harun ِal-Rashid Mausoleum
The Mausoleum of Harun al-Rashid is a joint mausoleum of the Abbasid caliph Harun al-Rashid with Ali al-Ridha in the city of Mashhad in Iran. Harun al-Rashid 

Abu Ja'far Harun ibn Muhammad al-Mahdi ibn Abdallah al-Mansur (149–193 AH), the fifth Abbasid Caliph. He was born in the city of Rayy in the year 149 AH (766) and died in the city of Tus (Mashhad today) in 193 AH (809). The death and burial of Harun al-Rashid 
Al-Rasheed, despite all his great deeds, felt the lack of resourcefulness in face of competitions and agendas within his Empire; the Al-Baramkeh catastrophe was not a solution to the situation. At the end of his days, he became lonely and ill. Hiding his illness from people, he uncovered his belly to one of his friends, displaying a band of silk on it. Al-Rasheed said to his friend: “This is an injury that I kept from all people. All including my sons are waiting for my death”. Al-Rasheed's illness got worse on his way to Khorasan to end the revolt of Rafi’ Ibn al-Layth. He died in the city of Tus (the current city of Mashhad in northeastern Iran) and was buried there in Jumada al-Thani in 193 AH / 809 AD. Ibn Battuta and the mausoleum 
The traveler Ibn Battuta described the shrine by saying: The honored scene has a great dome inside a corner adjacent to a school and a mosque, all of which are well built. In front of this is the tomb of Harun al-Rashid, and on it is a bench on which they place the candlesticks. Shrine location
