(1) To this world and the Hereafter. And they ask you about orphans. Say, "Improvement for them is best. And if you mix your affairs with theirs - they are your brothers.

(2) Have you not considered the assembly of the Children of Israel after [the time of] Moses when they said to a prophet of theirs, "Send to us a king, and we will fight in the way of Allah "? He said, "Would you perhaps refrain from fighting if fighting was prescribed for you?" They said, "And why should we not fight in the cause of Allah when we have been driven out from our homes and from our children?" But when fighting was prescribed for them, they turned away, except for a few of them. And Allah is Knowing of the wrongdoers.

(3) [theirs is] like the custom of the people of Pharaoh and those before them. They denied Our signs, so Allah seized them for their sins. And Allah is severe in penalty.

(4) And give to the orphans their properties and do not substitute the defective [of your own] for the good [of theirs]. And do not consume their properties into your own. Indeed, that is ever a great sin.

(7) [theirs is] like the custom of the people of Pharaoh and of those before them. They disbelieved in the signs of Allah, so Allah seized them for their sins. Indeed, Allah is Powerful and severe in penalty.

(8) [theirs is] like the custom of the people of Pharaoh and of those before them. They denied the signs of their Lord, so We destroyed them for their sins, and We drowned the people of Pharaoh. And all [of them] were wrongdoers.

(9) So when they took him [out] and agreed to put him into the bottom of the well... But We inspired to him, "You will surely inform them [someday] about this affair of theirs while they do not perceive [your identity]."

(10) Those who have believed and done righteous deeds - a good state is theirs and a good return.
