It is narrated from Awn bin Abdullah that Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) said: When the hadith of the Messenger of Allah (peace and blessings be upon him) is narrated to you, then be certain that it is the most agreeable, the most guiding, and the most pious matter.

It is narrated from Abu Abdur Rahman al-Sulami that Sayyiduna Ali, may Allah be pleased with him, said: When the hadith of the Messenger of Allah, peace and blessings be upon him, is narrated to you, then be certain that it is the most guided, the most pious, and the most conforming.

Whenever Sayyiduna Abu Hurairah (may Allah be pleased with him) narrated a hadith of the Messenger, he would say: The Messenger of Allah (peace and blessings of Allah be upon him) said:“Whoever deliberately attributes a lie to me, let him take his place in the Hellfire.”

Whenever Sayyiduna Ibn Abbas (may Allah be pleased with them both) narrated a hadith, he would say: When you hear me narrate a hadith of the Messenger, and you do not find it in the Book of Allah, nor do you find anything better with the people, then know that I have lied about the Prophet (peace be upon him).

It is narrated from Sulaiman al-Ahwal that Ikrimah (the freed slave of Sayyiduna Ibn Abbas, may Allah be pleased with them both) said: The ones who are most heedless of a scholar are his own household.
