[15]. One of the wives of the Prophet told him that in Abyssinia she saw a church full of images. The Prophet Muhammad said: “When a righteous man or saint among them dies they build a place of worship over his grave and set up images. They are the worst of all creatures before God. They combined the two evils; worshipping to the graves and making graven images.”
The Prophet Muhammad said: "Beware, those who preceded before you, used to make their Prophets’ graves into places of worship. Beware, don’t take any graves as places o f worship. I forbid you to do so.”
[16]. As soon as one remembers not saying inshā’ Allah - if God wills - concerning doing something in the future, he should say it. Also when one forgets something, he should mention Allāh by saying Laa ilaaha illal Laah 'there is no true God but Allâh only', so as to remember things.
[17]. Allāh runs the affairs of all His creation with great care, as much as He cared for these youth. He delegates this to none.
