Hadith.5013 - Talhah ibn Zayd narrated from Imam Jafar ibn Muhammad Al-Sadiq (as) from his father, Imam Muhammad ibn Ali Al-Baqir (as), that he said:
"A person should not be stripped of their clothing nor stretched out (meaning tied or extended) for any legal punishment."
Imam (as) also said
"The adulterer should be beaten in the state in which they are found; if they are found unclothed, they are beaten while unclothed, and if they are found clothed, they are beaten while clothed."
