(121) And if We had destroyed them with a torment before this (i.e. Messenger Muhammad صلى الله عليه وسلم and the Qur'an), they would surely have said: "Our Lord! If only You had sent us a Messenger, we should certainly have followed Your Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.), before we were humiliated and disgraced."

(122) Man is created of haste. I will show you My Ayat (torments, proofs, evidence, verses, lessons, signs, revelations, etc.). So ask Me not to hasten (them).

(123) We helped him against the people who denied Our Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.). Verily, they were a people given to evil. So We drowned them all.

(124) Thus have We sent it (this Qur'an) down (to Muhammad صلى الله عليه وسلم) as clear signs, evidence and proofs, and surely, Allah guides whom He wills.

(127) Then We sent Musa (Moses) and his brother Harun‎‎ (Aaron), with Our Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) and manifest authority,

(128) And those who believe in the Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) of their Lord;

(129) (This is) a Surah (chapter of the Qur'an) which We have sent down and which We have enjoined, (ordained its laws); and in it We have revealed manifest Ayat (proofs, evidence, verses, lessons, signs, revelations - lawful and unlawful things, and set boundaries of Islamic Religion), that you may remember.

(130) And Allah makes the Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) plain to you, and Allah is All-Knowing, All-Wise.
