As for “signs,” Ibn Kathir read it in the singular, “a sign”—that is, an admonition and a lesson. It was also said: something wondrous.
The other reciters read it in the plural: “signs.”
“For those who ask”: this was because the Jews asked the Messenger of Allah, may Allah bless him and grant him peace, about the story of Joseph, peace be upon him.
It was also said that they asked him why Jacob’s children had moved from Canaan to Egypt. So he related to them the story of Joseph, and they found it to correspond to what was in the Torah [and marveled at it] (1). This is the meaning of His saying: “signs for those who ask”—that is, evidence of the prophethood of the Messenger of Allah, may Allah bless him and grant him peace. It was also said: they are signs for those who ask and for those who do not ask, just as He says, “equally for all who ask” (Fussilat 10). (2)

His brothers saw in their father’s preference for him what they did not see in his treatment of themselves, so they made this statement. (3) “Though we are a strong group”: that is, a body of men; and they were ten.
Al-Farrā’ said: A strong group consists of ten or more.
It was also said: it consists of between one and ten.
It was also said: between three and ten.
Mujahid said: between ten and fifteen.
It was also said: between ten and forty.
And it was said: a group whose members support one another, having no singular form derived from its own wording, like the collective nouns nafar and raht.
“Surely our father is in clear error”: that is, in evident error in preferring Joseph and his brother over us. What is not meant by “error” is
