A group (Jamat) of people sleeping/staying in the masjid/markaz

Abu Hurairah (R.A) narrated, that “I saw seventy men from the As-Habussuffah neither of them possessed a robe, they either had loincloth (izaar) or from amongst some would reach half way down he shin and some till the heels, which they would hold tightly onto with their hands afraid of unveiling their private parts.
