Will the fingers and fingertips used for glorification (tasbeeh) bear witness on the prayer beads (khatim at-tasbeeh or subhah) on the Day of Resurrection, just as the fingertips bear witness directly when glorifying with them? And what is the difference between glorifying "on the fingertips" and glorifying "with the fingertips" in terms of testimony on the Day of Resurrection?

Counting tasbih on the fingertips is better than using prayer beads (misbaha), because the fingertips are a part of the worshipper's body, and they will be held accountable and questioned on the Day of Judgment regarding what they were used for, and they will bear witness to that. In contrast, the misbaha is an inanimate object that does not bear witness. Furthermore, there is a prophetic text (hadith (definition)) explicitly mentioning counting on the fingertips, which makes it more preferable and superior, as it encourages the use of body parts in good deeds.
