❓ Question: If before going to sleep one touched the water set aside for washing may it still be used to wash with in the morning?

If prior to going to sleep one accidentally touched the water in the basin prepared for the morning washing, the water nevertheless remains valid.¹ Furthermore, even if one intentionally scooped some water out of the basin prior to going to sleep the water nevertheless remains valid. However, if one cleaned his hands in the water that is in the basin, then even if this was done prior to going to sleep the water may not be used, as is the law regarding washing hands in the morning.
