Abu Juray al-Hujaymi (may Allah be pleased with him) narrates: I said: O Messenger of Allah, we are people of the desert, and we would like you to teach us a deed by which Allah may benefit us. He (peace and blessings be upon him) said: "Never belittle any good deed, even if it is that you pour from your bucket into the vessel of one asking for water, and even if it is that you speak to your brother with a cheerful face."
"And beware of letting your lower garment hang below the ankles, for that is part of arrogance, which Allah, the Mighty and Majestic, does not love."
"And if a man reviles you with something he knows about you, do not revile him with something you know about him, for the reward of that will be yours, and its burden will fall upon him."
