Images on Twitter show the Takfiri mufti’s arrival at a hotel in the British capital on Sunday.
The trip has sparked hot debates online, with many Twitter users slamming the radical Saudi cleric for journeying overseas while making divisive comments against Muslims and calling for action in Syria.
Arifi recently came under fire for his contentious remarks, with a senior Egyptian sheikh calling for a ban on such radical preaching.
Sheikh Mansour Mandour told Al-Alam on Sunday that the Saudi cleric’s comments should be judged by the criteria set in the Holy Qur’an and the Prophet’s Sunnah (sayings and teachings of Prophet Mohammad PBUH).
