Our mother Hazrat Aisha's (ra) knowledge
The world is founded on love. God’s Names ‘Ar-Rahman’ (The Most Merciful) and ‘Ar-Raheem’ (The Most Compassionate) manifest all over the world.
In the beginning of the verses of the Qur'an, God's Names Rahman and Rahim are recited. "Bismillahirrahmanirrahim". Rahman and Rahim, God; meaning God, the One Who knows and shows love very well and the One Who wants love from us. "Rahman" because He is the Protective, He is the One Who watches over, He is the One Who forgives, He is the One Who wants good for people.
The Names “Rahman, Rahim” are refreshing. They express refreshment. But in the Name "Al-Kahhar" love is hidden. God damns the unbelievers and saves Muslims. He takes Muslims' revenge; God takes the revenge of all those He loves. The Name Al-Kahhar is also a sign of love. His damning unbelievers stems from God's love for Muslims. That is why there is a hidden love in it.
Ar-Rahman and Ar-Rahim (Most Compassionate and All-Merciful). Both of those Names express love. Love is in the origin of both of those Names. Ar-Rahim means the One Who protects with love, the One Who looks after, the One Who is always after goodness, the One Who always creates with goodness.
