Al-Kahf 18:23

<h2>Saying "If Allah wills" when determining to do Something in the Future</h2><p>Here Allah, may He be glorified, shows His Messenger the correct etiquette when determining to do something in the future; this should always be referred to the will of Allah, the Knower of the Unseen, Who knows what was and what is yet to be and what is not to be, and how it will be if it is to be.
