Commentary on Tafsir al-Jalalayn: ((And as for Thamud, We guided them)) We made clear to them the path of guidance ((so they preferred blindness)) they chose disbelief ((over

As for the second division, he said: "

The Shaykh : Which one?
The student: Thamud.

The Shaykh : Because it is prohibited from inflection, and what about 'Aad?

This is inflection. The commentator said: We made clear to them the path of guidance "So the guidance here is guidance of clarification, meaning the truth was made clear to them. And know that everyone who disbelieves, he disbelieved after the truth had become clear to him when the Messenger came to him, because the Messengers (peace and blessings be upon them) clarify the truth; they do not leave anything that needs clarification without clarifying it. He said here: " meaning We made clear to them the path of truth, so the guidance here is guidance of clarification and direction. "

And His saying: the punishment of humiliation, means the humiliating punishment, because humiliation is degradation. The ba is for causality, and either it is a relative pronoun, in which case its referent is omitted, the estimation being: for what they used to earn, or it is a preposition of source, in which case it does not require a referent, and the estimation being: for their earning.
