The difference between al-Rahmaan and al-Raheem

 

What is the difference between al-Rahmaan and al-Raheem?.

Praise be to Allaah.
 

 

Al-Rahmaan and al-Raheem are two of the names
of Allaah which refer to Allaah’s attribute of Mercy. 

Al-Rahmaan refers to the vastness of Allaah’s
mercy, and al-Raheem refers to its effect on His creation. So al-Rahmaan is the Owner of vast Mercy, and al-Raheem is the Owner of Mercy that
encompasses His creation. 

Shaykh Ibn ‘Uthaymeen (may Allaah have mercy
on him) said: “Al-Rahmaan is the Owner of vast mercy, because the fa’laan form in Arabic indicates vastness and abundance, as it is said
rajal ghadbaan (a very angry man) when he is filled with anger. 

Al-Raheem is a name which refers to the
action, as the fa’eel form refers to the doer of an action. So the phrase al-Rahmaan al-Raheem indicates that the mercy of Allaah is vast,
as is understood from the name al-Rahmaan, and that it encompasses His creation, as is understood from the name al-Raheem. This is what some of
them meant when they said that al-Rahmaan refers to mercy in a general sense and al-Raheem refers to mercy that is specifically for the believers.
But what we have mentioned is more accurate.”
