Bukhari

Hadith Commentary:
It is a requirement of proper etiquette that vessels containing milk or water should always be kept covered and never left uncovered. By doing so, protection will be ensured.

Hadith Commentary:
Vocabulary of the Hadith:
Mukhammar:
Covered.
Wine is called khamr because it covers (veils) the intellect, and a woman's scarf is called khimar because it covers her head.

Benefits and Issues:
It is established from this hadith that
if one has to take any food or drink outside the house, it should be covered with something.
If it cannot be completely covered, then at least a piece of wood or something similar should be placed over it,
which in reality serves as a reminder that when covering, one should say "Bismillah" so that it remains protected from satanic influences.

Hadith Commentary:

Benefits and Issues:
From this hadith, it is understood that if there is no likelihood of anything falling into a vessel, then even if it has not been covered, food or drink from it may be used. However, it is contrary to the etiquettes of Islam that it should remain uncovered.

Benefits and Issues:
Benefit: When food and drink items need to be carried here and there for some distance, it is appropriate that they be covered while being transported.
