Hadith

Hadhrat Ibn Abbaas (radiallahu anhu) narrates: “I was (once) behind Nabi (sallallahu alayhi wasallam) when he said to me: ‘O son! I shall inform you of a few things. Remember Allah and He will protect you. Remember Allah and you will find Him close to you. When you have to ask for something, ask of Allah Ta’ala. When you require aid, seek His Aid. Believe firmly that if all creation desires to benefit you in anything, they can never benefit you but that which Allah has decreed for you. If they all unite to harm you, they will not be able to harm you in anything, but that which Allah has decreed for you.”
