What is the ruling on the group that claims the Prophet, peace and blessings be upon him, knew the unseen, re-prays behind the imams of the Two Holy Mosques, seeks intercession through the dwellers of graves, and declares as disbelievers those who do not belong to the four imams?

These actions are satanic extravagances that contradict the guidance of the Pious Predecessors. Claiming that the Prophet, may Allah’s prayers and peace be upon him, has knowledge of the unseen is a prohibited exaggeration. Going to graves to supplicate to their occupants and seek their help is an act of disbelief (kufr). And whoever makes angels and prophets intermediaries, supplicating to them and asking them to bring benefits and avert harms, has committed disbelief (kufr) by the consensus of Muslims. Repeating prayers that they perform behind the imams of Ahl al-Sunnah is the doctrine of the Khawarij, for prayer behind a just Muslim is valid by the agreement of Muslims. Declaring a Muslim to be a disbeliever is a severe threat, especially declaring reforming scholars to be disbelievers. These individuals should be advised with wisdom, but if they persist in their deviation, boycotting them becomes obligatory.
