Ruling on calling Mount ‘Arafah Jabal al-Rahmah
Question

                Some people call Mount ‘Arafah Jabal al-Rahmah (the Mount of Mercy). What is the ruling on this name, and is there any basis for that?.
Praise be to Allah.Shaykh Muhammad ibn ‘Uthaymeen (may Allaah have mercy on him) answered this question by 
    saying: 
I do not know of any basis for this name in 
    the Sunnah, i.e., that the mountain in ‘Arafah, by which the Prophet  (peace and blessings of Allaah be upon him) stood, is called Jabal 
    al-Rahmah (the Mount of Mercy). Since there is no basis for that in the Sunnah, it should not be called by that name. Perhaps those who call it 
    thus realize that this is a great standing in which those who stand at ‘Arafah receive the forgiveness and mercy of Allaah, so they called it by 
    this name. But it is better not to use this name, rather it should be called Jabal ‘Arafah (Mount ‘Arafah), or the mountain by which the Prophet 
     (peace and blessings of Allaah be upon him) stood, etc.
