The zakah collector taking a hobbling rope with the camel

Yahya bin Sa'id said: The Sunnah way is that the zakah collector takes, with each camel, a rope (with which it is tied) as well, and with two camels, two foot-tying ropes and one other rope.

Ibrahim narrates that Sayyiduna Abu Bakr al-Siddiq (may Allah be pleased with him) said: If those people refuse to give me even a piece of rope which they used to give to the Prophet (peace and blessings be upon him), I will wage jihad against them.
