O Believers, what is the matter with you that when you are asked to march forth in the way of God, you cling to the earth?

Do you prefer the life of this world to the life of the hereafter?

The comfort of this life is so little compared to that of the life of the hereafter.
If you do not march forth, He will inflict on you a painful punishment and replace you with other people, and you cannot harm Him at all, for God has power over everything.

If you do not help him (the Prophet), it does not matter: God did help him while the unbelievers drove him out of his town, the second of the two, while the two were in the cave and (enemy came to the opening of the cave) he said to his companion (Abu Bakr, first of the rightly guided caliphs), “Do not worry, God is with us.”

So God sent down his serenity on him and strengthened him with forces which you could not see; thus, He made the word of the unbelievers lowest, while the word of God remained supreme. God is All-Mighty, All-Wise.
