Hazrat Shu'ayb narrates that Hazrat Abu Al-'Aliyah used to teach people the Qur'an: So when he intended to correct someone's mistake, he would not say: "It is not like this or that." Rather, he would say: "Recite the verse like this." So I mentioned this to Ibrahim, and he said: "I think your companion has heard this hadith: Whoever denies a single letter of the Qur'an has indeed denied the entire Qur'an."

32108 - I mentioned it to Ibrahim, and he said: I think your companion has heard that whoever disbelieves in a single letter of it has disbelieved in all of it.

Hazrat Alqamah narrates that I stopped Hazrat Abdullah bin Mas'ud (may Allah be pleased with him) while he was reciting the Qur'an, so he said: "How is it according to your opinion?" I said: "You recited as it is present in the Qur'an except for one letter. You recited it like this and like that."

Hazrat A'mash says that I recited the Qur'an to Ibrahim. When I passed by a certain word, he stopped me at it. He did not say to me that it is not like this or like that. Rather, he said: Hazrat Alqamah used to recite this verse like this and like that.

Hazrat A’mash narrates that Ibrahim said to me: Indeed, Ibrahim al-Taymi wishes that you teach him the recitation of Hazrat Abdullah. I said: I do not have the strength. He said: Why not, for indeed this is his intention. A’mash says: When I saw that this is what he wanted, I said: Fine, it will be in your presence. So we discussed the letters of Hazrat Abdullah. Then he said: That is sufficient for me. I said: Why do you dislike teaching in this way? He said: I dislike that I say about any verse that it is like this, but it is not so, or that I say: there is a waw in it, and there is no waw in it.

Ibrahim narrates that a man asked Hazrat Ibn Mas’ud about the pronunciation of this verse:“And those who believed and their offspring followed them in faith.”So that man began to say“dhurriyyatahum.”Then he kept repeating this word again and again. And you did not say: that it is not like this.

Hazrat A'mash says that Ibrahim said: I dislike to testify regarding the Qur'an, lest I say: "It is like this," while it is not so.
