Be mindful of Allah and He will protect you

Ibn Abbas reported: I was riding with the Messenger of Allah, peace and blessings be upon him, and he said 

Young man, I will teach you some words. Be mindful of Allah and he will protect you. Be mindful of Allah and you will find him before you. If you ask, ask from Allah. If you seek help, seek help from Allah. Know that if the nations gathered together to benefit you, they will not benefit you unless Allah has decreed it for you. And if the nations gathered together to harm you, they will not harm you unless Allah has decreed it for you. The pens have been lifted and the pages have dried.
