The Pen - 68:23
So they set out, talking among themselves.
In the context of verses 17, 18...28; for nothing, for nothing, we should not say, "I will do this tomorrow," but we should say, "By Allah's permission, if Allah wills."
The Cave/18:23
"Do not say of anything, "I will do it tomorrow."
The Cave/18:24
"But remember your Lord, saying, "If Allah wills (I will do it)."If you forget, then say, "Perhaps my Lord will make me better next time."
The Cave/18:69
"He said: "If Allah wills, you will find me patient, and I will not oppose you in anything."
The Man/76:30

Prophet Jonah/10:16
"Say: "Had Allah not willed, I could not have recited it to you and you would not have known of it. I lived among you for a lifetime before that, do you not understand?"
The Cow/2:102
"They followed what the devils told them about the authority of Solomon. But Solomon did not disbelieve; it was the devils who taught the people sorcery and what was revealed to the two angels Harut and Marut in Babylon. These two said: "This is a test; do not be ungrateful (by misusing this knowledge)."But they used what they learned from those two to drive a wedge between a husband and his wife. But they could not harm anyone without Allah´s permission. They were learning that which harmed them, not that which benefited them. Moreover, they knew well that those who were its customers had no share in the Hereafter. How bad is that for which they sold their personalities. If only they knew!"
The Iron/57:22
There is nothing in the earth and among you that is not recorded in a Book before We created it. Surely this is easy for Allah.
The Iron/57:23
This is so that you may not grieve for what you have lost, and that you may not be spoiled by what He has given you. Allah does not love those who are proud and boastful.
