Explaining the practice of exposing the shoulder during sa'y and instructing the pilgrims performing 'Umrah

The questioner:
Honorable Shaykh, may Allah grant you success, this questioner says: Every time I go to perform 'Umrah, when I do the sa'y between al-Safa and al-Marwah,

The Shaykh:
every time.

The questioner:
He says: Every time I go to perform 'Umrah, when I go to do the sa'y, I see many of the pilgrims still exposing their shoulders while they are doing the sa'y between al-Safa and al-Marwah. So I instruct them to cover their right shoulder, because the practice of exposing the shoulder has ended with the tawaf. He says: I do this throughout the period of the sa'y. Is there any problem with this?

The Shaykh:
May Allah reward you with good. If you are explaining the Sunnah to them, this is among the recommended practices (mustahabb) that you explain to people, or it may be obligatory that you teach the ignorant. Yes.
