The ruling on taking knowledge from those who praise the existing groups

Question:
The questioner also asks: Is it permissible to take knowledge from those who praise the groups currently present in the scene?

Answer:
As we mentioned, hold fast to the Book and the Sunnah. If they bring forth the Book and the Sunnah, the Sunnah of the Book of Allah and the Sunnah of His Messenger, then take hold of that truth. The truth is the lost property of the believer; wherever he finds it, he takes it. But if they contradict what the Messenger (peace and blessings be upon him) and his Companions were upon, then reject this and stay away from it. Yes, look at the methodology, not at the groups and the differing factions. Look at the methodology. If it is truth, adhere to it with whoever it is with, and if it is falsehood, reject it with whoever it is with.
Those who draw up for themselves conventional methodologies that they establish, or that their leaders establish for them, and they abandon the methodology of the Messenger (peace and blessings be upon him) and his Companions, these are the people of misguidance.
