It is narrated from Sayyiduna Malik bin Nadlah al-Jushami (may Allah be pleased with him) that he said: I said: O Messenger of Allah! I passed by a man, and he neither hosted me nor showed me hospitality. Then, if he passes by me, should I show him hospitality? He (peace and blessings be upon him) said: "Rather, show him hospitality."
