What is the ruling on the hand sweating while holding the Qur’an or browsing religious content on a smartphone, knowing that the hand naturally sweats a lot?

Sweating of the hand when holding the Mus'haf (Qur'an), which is difficult to guard against, and there is no statement from the people of knowledge (scholars) regarding the need to place a barrier on the hand because of it. Sweat is pure, and one should not pay attention to that (the sweating) to avoid falling into whispers (waswas).
