What is the ruling on supplicating for the deceased woman with mercy and forgiveness while standing at her head when she is being shrouded, and how many individuals are allowed to enter to shroud her?

Supplicating for the deceased is recommended at any time. There is no fixed Sunnah for supplication during the washing or shrouding of the deceased. As for the number of people preparing the deceased, there is no specific religious text determining it, but it is recommended that their number be odd (three or more) according to need.
