Sayyidina Mughirah bin Shu'bah radiallahu anhu relates:
"Dihyah Kalbi sent to Rasulullah Sayyidina Rasulullah sallallahu alaihe wasallam as a gift two khuffs. In another narration it is stated that with the khuffs, a jubbah (a long coat) was also sent. Rasulullah Sayyidina Rasulullah sallallahu alaihe wasallam did not inquire if the skin was from slaughtered animals or not". (IT)
