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.

Sayyiduna Abu Musa Ash'ari (may Allah be pleased with him) said: The Children of Israel wrote a book, they followed it and abandoned the Torah.

Affan (bin Abdullah bin Mirdas al-Muharibi) narrated from his father (Abdullah) that I heard Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) saying: Indeed, some people listen to my words and then go and write them down, and I do not make it permissible for anyone to write anything except the Book of Allah, the Mighty and Majestic.

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.
