What is the position regarding the principle of rapprochement between Sunnis and Rafidah, taking into consideration the history of the Rafidah?

Bringing together the Rafidah and the Sunnis is not possible due to the difference in عقيدة (creed/belief). The Sunnis believe in the oneness of God (Tawhid (definition) Allah), dedicating worship solely to Him, that no one else should be invoked alongside Him, and that God knows the unseen. They love and are pleased with the Companions, believing them to be the best of creation after the Prophets, and that the best of them are Abu Bakr, then Umar, then Uthman, then Ali. As for the Rafidah, their belief contradicts this, so it is not possible to unite them.
