Abdullah bin Awn said: Muhammad bin Sirin (may Allah have mercy on him) said to me: It is narrated from our master Zaid bin Thabit (may Allah be pleased with him) that Marwan bin Al-Hakam, who was the governor of Madinah, wanted me to write something for him, but I did not do so. The narrator said: The Amir (respected one) had a curtain placed between himself and the rest of the women of the household (the people of the house), then the governor’s (Marwan’s) companions came to him at that place and began to converse. Then Marwan turned to his companions and said: I think we have betrayed them. Then he turned to me (Zaid bin Thabit), and I said: What kind of betrayal? He said: I think we have betrayed you. I said: What is the matter? He said: We had ordered a man to sit behind that curtain and to write down whatever fatwa these people give and whatever you say.

Mansur (bin al-Mu'tamir) said: I said to Ibrahim that Salim (ibn Abi al-Ja'd) is more proficient than you in hadith. Ibrahim said: Because Salim used to write (the hadiths) down.

Amr bin Qais said: Upon the death of Sayyiduna Muawiyah (may Allah be pleased with him), I went with my father to offer condolences and congratulations for the caliphate to Yazid bin Muawiyah at Hawwarin. We saw that in his mosque, a man was saying: Beware! Among the signs of the Hour is that the wicked will be raised up and the good will be brought down. Listen! Among the signs of the Hour is that speech will be widespread and action will be preserved. Listen! Among the signs of the Hour is that the "Mathnaat" (secondary book) will be read and no one will change it. It was asked: What is this "Mathnaat"? He replied: Requesting to write a book other than the Qur'an. Therefore, hold fast to the Qur'an; through it you have been guided, through it you will be rewarded, and about it you will be questioned. I did not recognize who this man was. Then I narrated this hadith in Homs, and a man from the group said to me: Do you not know him? I said: No. He said: This was Sayyiduna Abdullah bin Amr bin al-As (may Allah be pleased with him).

Murrah Hamdani said that Abu Qurrah Kindi brought a book from Syria and handed it over to Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him). He read the book, called for a plate and water, and washed it thoroughly, and said: The people before you were destroyed because they followed other books and abandoned their original book. It is narrated from Husayn: Murrah said: If it had been something from the Book and the Sunnah, Sayyiduna Ibn Mas'ud (may Allah be pleased with him) would not have erased it; it was a writing from the books of the People of the Book.

Yahya bin Ja'dah said: A written shoulder bone was brought to the Prophet Muhammad (peace be upon him). He (peace be upon him) said: "It is sufficient misguidance for a people that they show indifference to what their Prophet has brought, and turn to another Prophet instead of their own Prophet, or turn to another book instead of their own book." And in support of this, Allah the Exalted revealed this verse: «﴿أَوَلَمْ يَكْفِهِمْ أَنَّا أَنْزَلْنَا عَلَيْكَ الْكِتَابَ يُتْلَى عَلَيْهِمْ إِنَّ فِي ذَلِكَ لَرَحْمَةً وَذِكْرَى لِقَوْمٍ يُؤْمِنُونَ﴾» [عنكبوت: 51/29] "Is it not sufficient for them that We have sent down to you the Book which is recited to them? Indeed, in it is mercy and a reminder for a people who believe."

Ash'ath (ibn Abi al-Sha'tha) narrated from his father, who was among the students of Sayyiduna Abdullah ibn Mas'ud (may Allah be pleased with him), that I saw with a man a scroll in which something was written: «سبحان الله والحمد لله ولا إله إلا الله والله أكبر» . I said: Write it for me as well, but he acted stingily, then he promised me that he would give me that scroll. Then I came to Sayyiduna Abdullah ibn Mas'ud (may Allah be pleased with him) and saw that same scroll was before him. He said: In this writing there is innovation, trial, and misguidance. It was things like this that destroyed those before you; they wrote it, their tongues relished it, and it settled in their hearts. So I urge every man that if he knows the place of any such book, he should inform me, and I make him swear. Shu'bah said: And he made them swear. The narrator said: I think he swore and said that if that book was in any place in India, which would be far from Kufa, I would reach there even if I had to go on foot.

Ibn Shubrumah said: I heard Imam Sha’bi, may Allah have mercy on him, say: I have never written black over white, and I have never requested any person to repeat a hadith to me.
