Is it true that 'Abd Allah ibn Mas'ud did not consider the two protective surahs to be part of the Qur'an and did not include them in his mushaf?

Eid Abbasi : Another question: Is it true that 'Abd Allah ibn Mas'ud (may Allah be pleased with him) did not consider the two protective surahs to be part of the Qur'an and did not include them in his mushaf? And that Ubayy ibn Ka'b included the supplication of qunut in his mushaf and made it into two surahs? May Allah reward you with good.

The Shaykh : What I recall regarding this question is that it has two parts, as you heard. Regarding Ibn Mas'ud, it is authentic from him, and there is nothing strange about it. This is evidence that the matter is as Allah (Mighty and Majestic) said, addressing every one of us in His general statement: . Ibn Mas'ud (may Allah be pleased with him), who was among the early ones to enter Islam, still missed some things, some of which were very, very important. This includes what is mentioned in this question. He did not understand from what he heard from the Prophet (peace and blessings be upon him) that the two protective surahs, and , are two surahs of the Noble Qur'an. Rather, he understood that they were protective supplications, a du'a like this. Therefore, out of his concern that nothing strange to him be included in the Qur'an in the mushaf containing the Qur'an, he would scrape off every page containing these two surahs. This was because he did not know that they were part of the Qur'an. However, this is a characteristic of the Qur'an. The Qur'an was not collected from one person, but rather from dozens, indeed hundreds of people, after it had been written on sheets of a strange type in those times, consisting of animal shoulder bones, palm leaves, and the like. This is how Allah (Mighty and Majestic) enabled hundreds of Companions to memorize the entire Qur'an in their hearts first, and to write it down in the means known to them second.
Because of this fact, some Western writers have admitted that no other religion is like Islam in that its first constitution, which is the Qur'an, is transmitted by mass transmission (mutawatir) and preserved. Many of them testify to this. We do not boast, but we say: "The merit is what the enemy testifies to." It does not harm us at all that this narration is authentic and established from Ibn Mas'ud. Rather, we take a lesson from the establishment of this narration to counter the extremists among Muslims, both past and present, who consider pointing out the error of a certain shaykh to be a snide remark, an attack, or a blemish. No, "It is sufficient for a person to be noble that his faults are counted." Ibn Mas'ud was a noble Companion who had a virtue for Islam and the Muslims in that he transmitted to us hundreds of legal rulings. He was among the preservers of the Qur'an, and they were skilled in its recitation. The Messenger would praise him and say: , , meaning the son of the mother of 'Abd Allah ibn Mas'ud. This is a very nice way of expressing it.
The point is: If some errors are found in this noble man, first of all, he is not held accountable for them at all, because they were not intentional on his part. On the contrary, as you just heard, he would scrape and rub out these two surahs to protect the Noble Qur'an from additions. So he is not held accountable for this at all. Therefore, there is no blemish in stating this fact explicitly. Rather, we benefit from it, as we said, that no matter how high a person rises, he must have some errors, as came in some mawquf hadiths. Some narrate from Ibn 'Abbas, and some from some of the Tabi'un. Finally, it became famous from Malik: "None of us is there except that he was corrected and corrected others, except the owner of this grave," and he pointed to the grave of the Prophet (peace and blessings be upon him and his family).
Therefore, the Muslims did not care at all about this narration and this error that came from Ibn Mas'ud. So the two surahs were recorded in the mushaf, and they are mass-transmitted (mutawatir) along with the entire mushaf.
Also, from the opinion of Ibn Mas'ud is that when he prayed—and I mention this not as a blemish, but only as a lesson—when he prayed, he would perform "tathbīt." Tathbīt, according to jurists and hadith scholars, is to interlace the fingers of the two hands like this, then insert them while bowing between the thighs, and not grasp the knees with the hands as is the Sunnah. This is established and authentic from Ibn Mas'ud as well, and there is no room for denying it. So the Muslims did not adopt this. Why? Because Allah (Mighty and Majestic) inspired other Companions to preserve the Sunnah for us, and indeed to clarify to us that Ibn Mas'ud, in his tathbīt, only preserved what was prescribed in the early Islam. It is established that a son of Sa'd ibn Abi Waqqas (may Allah be pleased with him) was in Kufa, where 'Abd Allah ibn Mas'ud was. One day, he prayed next to Ibn Mas'ud and grasped his knees with his hands as we do today. So, out of Ibn Mas'ud's concern to preserve what he knew from the Messenger (peace be upon him), he took the hands of the man, the son of Sa'd, in prayer and interlaced them, pressing them between his thighs. After the prayer, it appears that he explained to him that this is the Sunnah and this is how he saw the Messenger (peace be upon him) doing it. The son of Sa'd returned to his father in Madinah. Sa'd ibn Abi Waqqas was one of the ten promised Paradise. He related to him the story of Ibn Mas'ud with him. He said, "He spoke the truth—look at this too, the etiquette and gentleness—he said: 'My brother 'Abd Allah ibn Mas'ud spoke the truth. We used to do that, then we were commanded to grasp the knees.'" There is no blemish in this. He missed something, but he preserved things and things and many things. This is what comes to our mind.
As for Ubayy ibn Ka'b and that he used to write in his mushaf: "O Allah, we seek Your help," I have passed by something of this in the past, but I do not remember if the narration from him is authentic or not. Perhaps it will be easy for me to review that and I will bring you the answer, if Allah wills, in the next lesson, by the permission of Allah. This is enough for now, and praise be to Allah, Lord of the worlds.
Is there anything?
