Allah's statement,
    ﴿وَمِنَ الأَنْعَـمِ حَمُولَةً وَفَرْشًا﴾
    (And of the cattle (are some) for burden and (some smaller) for Farsh.) means, He
    created cattle for you, some of which are suitable for burden, such as camels, and
    some are Farsh. Ath-Thawri narrated that Abu Ishaq said that Abu Al-Ahwas said that
    `Abdullah said that `animals for burden' are the camels that are used for carrying
    things, while, `Farsh', refers to small camels. Al-Hakim recorded it and said, "Its
    chain is Sahih and they did not record it.'' `Abdur-Rahman bin Zayd bin Aslam said
    that `animals for burden' refers to the animals that people ride, while, `Farsh'
    is that they eat (its meat) and milk it. The sheep is not able to carry things,
    so you eat its meat and use its wool for covers and mats (or clothes). This statement
    of `Abdur-Rahman is sound, and the following Ayat testify to it,
    ﴿أَوَلَمْ يَرَوْاْ أَنَّا خَلَقْنَا
        لَهُم مِمَّا عَمِلَتْ أَيْدِينَآ أَنْعـماً فَهُمْ لَهَا مَـلِكُونَ - وَذَلَّلْنَـهَا
        لَهُمْ فَمِنْهَا رَكُوبُهُمْ وَمِنْهَا يَأْكُلُونَ ﴾
    (Do they not see that We have created for them of what Our Hands have created, the
    cattle, so that they are their owners. And We have subdued them unto them so that
    some of them they have for riding and some they eat.) ﴿36:71-72﴾, and,
    ﴿وَإِنَّ لَكُمْ فِى الاٌّنْعَـمِ
        لَعِبْرَةً نُّسْقِيكُمْ مِّمَّا فِى بُطُونِهِ مِن بَيْنِ فَرْثٍ وَدَمٍ لَّبَنًا
        خَالِصًا سَآئِغًا لِلشَّارِبِينَ ﴾
    (And verily, in the cattle, there is a lesson for you. We give you to drink of that
    which is in their bellies, from between excretions and blood, pure milk; palatable
    to the drinkers.) ﴿16:66﴾, until,
    ﴿وَمِنْ أَصْوَافِهَا وَأَوْبَارِهَا
        وَأَشْعَارِهَآ أَثَـثاً وَمَتَـعاً إِلَى حِينٍ﴾
    (And of their wool, fur and hair, furnishings and articles of convenience, comfort
    for a while.) ﴿16:80﴾.
