The ruling on tasbih after the obligatory prayer and others using a misbaha?

Question:
He says: Honorable Shaykh, may Allah grant you success, what is the ruling on tasbih after the obligatory prayer or others using a misbaha?

Answer:
If he adopts it as a religion and believes that there is blessing in it and that this is prescribed, then it is a bid'ah (religious innovation). But if he wants to count the tasbih so he does not make a mistake, like counting with his fingers or with pebbles, then there is no harm. He adopts this from the category of the permissible only, so there is no harm. But if he adopts it from the category of the sunnah (recommended practice), then it is a bid'ah and it is not permissible. Yes, and this is with the Sufis; they are the ones who commit to misbahas and amulets and hang them around their necks. And the emblem of the Sufis, if he believes that there is blessing in it and that it is an emblem of worship.
