Whoever thinks that Allah will not assist him in this life and the hereafter, let him stretch a rope to the ceiling, then let him cut (it) off, then let him see if his struggle will take away that at which he is enraged.

And strive hard in (the way of) Allah, (such) a striving a is due to Him; He has chosen you and has not laid upon you an hardship in religion; the faith of your father Ibrahim; He named you Muslims before and in this, that the Messenger may be a bearer of witness to you, and you may be bearers of witness to the people; therefore keep up prayer and pay the poor-rate and hold fast by Allah; He is your Guardian; how excellent the Guardian and how excellent the Helper!
