It is narrated from a Companion (may Allah be pleased with him) that once I was present in the service of the Prophet (peace and blessings be upon him) when a man came and addressing the Prophet (peace and blessings be upon him) said, "Are you the Messenger of Allah?" The Prophet (peace and blessings be upon him) replied, "Yes!" He asked, "What do you invite to?" The Prophet (peace and blessings be upon him) said, "I invite to Allah, Who is One. Tell me, who is that Being that when a calamity befalls you and you call upon Him, He removes your calamity? Who is He that when you are afflicted with drought and you supplicate to Him, He brings forth produce? Who is He that when you lose your way in a desert or wilderness and you supplicate to Him, He brings you back?" Hearing this, that person became Muslim and said, "O Messenger of Allah! Advise me." The Prophet (peace and blessings be upon him) said, "Do not abuse anything." He says that after that, I never abused even a camel or a goat since the Prophet (peace and blessings be upon him) advised me. "And do not show aversion to any good deed, even if it is meeting your brother with a cheerful face, pouring water from your bucket into the vessel of one who asks for water, and tying your lower garment up to half the shin; if you cannot do that, then up to the ankles, but avoid letting the lower garment hang down, for this is arrogance, and Allah does not like arrogance."
