Musnad Ahmad Hadith 20636

It is narrated from a Companion that once I was present in the service of the Prophet (peace be upon him) when a man came and addressing the Prophet (peace be upon him) said, "Are you the Messenger of Allah?" The Prophet (peace be upon him) replied, "Yes." He asked, "What do you invite towards?" The Prophet (peace be upon him) said, "I invite towards Allah, Who is One. Tell me, who is that Being that when a calamity befalls you, 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 desolate wilderness and you supplicate to Him, He brings you back?" Hearing this, he became Muslim and said, "O Messenger of Allah, advise me." The Prophet (peace be upon him) said, "Do not abuse anyone." He says that after that, I did not even abuse a camel or a goat since the Prophet (peace 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 while talking, or pouring water from your bucket into the vessel of one who asks for water. And tie your lower garment up to half the shin; if you cannot do this, then up to the ankles, but avoid letting the lower garment hang down, for this is arrogance, and Allah does not like arrogance."
