The Quran

وَاللَّهُ جَعَلَ لَكُم مِن بُيوتِكُم سَكَنًا وَجَعَلَ لَكُم مِن جُلودِ الأَنعامِ بُيوتًا تَستَخِفّونَها يَومَ ظَعنِكُم وَيَومَ إِقامَتِكُم ۙ وَمِن أَصوافِها وَأَوبارِها وَأَشعارِها أَثاثًا وَمَتاعًا إِلىٰ حينٍ

Muhammad Asad

And God has given you [the ability to build] your houses as places of rest, and has endowed you with [the skill to make] dwellings out of the skins of animals¹ - easy for you to handle when you travel and when you camp - and [to make] furnishings and goods for temporary use of their [rough] wool and their soft, furry wool² and their hair.

The term julud (sing. jild) denotes, literally, "skins", but apparently comprises here also the wool which grows on the skins of domesticated animals. It is to be noted that in Arabian usage the noun bayt ("house") signifies not only a solid building but also a "tent" - in brief, every kind of dwelling, whether permanent or temporary.
Wabar (here given in its plural, awbar) is the soft wool growing on the shoulders of camels ("camel-hair"), used in the weaving of fine cloths and sometimes also of bedouin tents.
