“I once heard abu ‘ Abd Allah (a.s.), saying, ’It is not unlawful to look at the heads of the people of al-Tihamah and Arabs who live in black (tents) and al-‘Aluj (faithless uneducated people) because even if they are prohibited they do not listen.’ He (the Imam) said, ‘In the case of insane and those whose reason is defeated (very weak) it is not unlawful to look at their hairs and body as long as it is not an intentional look.’”
