(37) And do not walk upon the earth exultantly. Indeed, you will never tear the earth [apart], and you will never reach the mountains in height.
(83) That home of the Hereafter We assign to those who do not desire exaltedness upon the earth or corruption. And the [best] outcome is for the righteous.
I came to the Messenger of Allah (PBUH) and said: O Messenger of Allah, we are a people of the desert. Teach us something with which Allah will benefit us. He said: Do not belittle any good deed, even if it is pouring water from your bucket into the vessel of one who is asking for water, or speaking to your brother with a cheerful face. Beware of trailing your garment, for that is a form of arrogance, and Allah does not like arrogance. If someone insults you for something he knows about you, do not insult him for something you know about him, for you will be rewarded, and the consequences are upon the one who said it.
