Sayyiduna Jabir bin Atik (may Allah be pleased with him) said that the Messenger of Allah (peace and blessings be upon him) said: "Soon riders will come to you who will be disliked. When they come to you, welcome them; if they make a demand, fulfil it. If they act justly, it is for their own good, and if they do wrong, its burden is upon them. Keep them pleased, for the completeness of your zakah lies in their being pleased, and let them pray for you."
The chain of this hadith from Abu al-Ghusn is reported inconsistently.
