Is it permissible to read books that are overflowing with religious innovations (bid'ah), by analogy to the taking of the words of al-Harith al-Muhasibi by the Shaykh al-Islam?

The questioner:
He says: Honorable Shaykh, may Allah grant you success, regarding books that are overflowing with religious innovations (bid'ah) and doctrinal deviations, are their books read and the truth therein taken, by analogy to the taking of the words of al-Harith al-Muhasibi by the Shaykh al-Islam?

The Shaykh:
Yes, the truth is taken and used as evidence. If this is the case, despite the errors he is in, if he speaks a truth, it is taken. The truth is taken; it is the lost property of the believer, and it is taken wherever it is found. As for falsehood, it is rejected. Falsehood is rejected from whoever said it, whoever he may be. Yes.

The presenter:
He says: Honorable Shaykh, may Allah grant you success, is it understood from the word...

The Shaykh:
If we respond to the people of falsehood, do we reject the truth that is with them? We take the truth that is with them. Yes.
