What is the ruling on attending a Quran memorization session while avoiding Hadith sessions with the Justice and Benevolence Group, whose guide narrates Hadiths and sayings of Muhyiddin ibn Arabi?

One must be scrupulous in judging groups and individuals. Ibn Arabi is among the shaykhs of misguidance. If you ascertain that a group reiterates the words of Ibn Arabi and follows his innovations, then you must beware of them and avoid taking knowledge from them, in preservation of your religion and creed, especially if you are not firmly grounded in knowledge. The people of Sunnah are many, and knowledge can be taken from them. If you reach a level of knowledge where you can distinguish truth from falsehood, then you may learn from someone who is involved in an innovation, while advising him and clarifying the danger of his innovation.
