Do not take an old, decrepit, broken-limbed, sick or unsound animal. Do not entrust the animals (for custody) except to one whom you trust to take care of Muslims’ property till he hands it over to their chief who will distribute it. Do not entrust it to anyone except he who is a well wisher, God-fearing, trustworthy and watchful, and who is not harsh on Muslims’ property, nor makes them run too much, nor tires them, nor labours them. Then send to us all that you have collected and we shall deal with it as Allāh has ordered.
