At this point, Moses (u) did not use forgetfulness as an excuse, either because he did not forget or he opted for changing a deplorable thing -which was taking a human life unjustly- in fulfilling his commitment; or he may have forgotten, but did not want to repeat the same excuse. Ibn Ashur: 16/6.
Question: This time, Moses (u) did not use forgetfulness as an excuse, why?

Another important principle with regard to one man handling the wealth of another is that if it is done in a manner that serves the latter's interests and wards off harm, it is permissible for him to do that, even without permission, and even if that involves causing some damage to the property of the other person, such as when Al-Khidr scuttled the ship in order to render it defective, so that it would be safe from being seized unlawfully by the unjust king. Based on that, if a fire or flood or the like occurs in the house or property o f a man, then it is permissible to damage part of the property or demolish part of the house for the sake of saving the rest. In fact, that is prescribed to protect the wealth and property of the other person. Al-Saadi: 485.
Question: Scholars inferred an important principle from this verse, what is it?

Qatadah said: "His parents rejoiced when he was born, and grieved for him when he was killed. If he had stayed alive, he would have been the cause of their doom. So, let a man be content with the decree of Allah, for the decree of Allah for the believer, if he dislikes it, is better for him than if He were to decree something that he likes for him." Ibn Kathir: 3/96.
Question: How should the Muslim deal with griefs and afflictions?

This Indicates that a righteous person's offspring will be taken care of, and that the blessing of his worship will extend to them in this world and in the Hereafter. This will occur through his intercession for them, as well as, their status being raised to the highest levels of Paradise, so he will be comforted by seeing them. Ibn Kathir: 3/97.
Question: Your righteousness may benefit your offspring. Explain in light of this verse.

This indicates that Allah protects the righteous person and his offspring, even if they are far away from him. It is narrated that Allah protects the offspring of a righteous person up to seven generations. Al-Qurtubi: 13/356.
Question: What is the immediate reward for a person's righteousness?

(So your Lord willed), he attributed the will here to Allah since it is part of the unseen which is known only to Allah. However, Al-Khidr attributed the will to himself when damaging the ship, (I wanted to make it defective), since harm is not attributed to Allah out of reverence for Him. This is similar to what Abraham (u) said, (and when I am ill, it is He who cures me) [26:80]. Ibn Juzay: 1/518.
Question: Al-Khidr attributed the will to himself when damaging the ship, but attributed the will to Allah when mending the wall. Why?

(I did not do it of my own accord) not my choice and view, rather, I did it by the command of Allah. Al-Baghawi: 3/55.
Question: Does a scholar do what he wants, or follows and adheres to the command of Allah?
