Shamail Tirmidhi

Buraydah (radiallahu anhu) says, "Najaashi sent two simple black coloured socks as a gift to Sayyidina Rasulullah sallallahu alaihe wasallam. He wore these and made mash over them after performing wudu".

"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".
