Qasim said: After knowing Allah Almighty’s right upon himself, if a man lives as an ignorant person, then this is better for him than to say something about what he does not know.

Ayyub said: I heard Qasim, he was asked, so he said: By Allah, we do not have knowledge of all the things you ask us about, and if we had knowledge, we would neither hide it from you nor would it be permissible for us to hide it.

Abdullah bin Awn said: Qasim (bin Muhammad al-Faqih) was asked about something, so he said: I neither need advice nor am I worthy of it.

Yahya said: I said to Qasim, "It is very hard for me that someone asks you a question and you express ignorance about it, even though your father was the Imam of the time." He replied, "It is even harder and more severe (a harsher matter) with Allah and with those who have understanding about Allah, that I should give a fatwa without knowledge or narrate something from an unreliable narrator."

Musayyib bin Rafi’ said that when people faced an issue about which there was no narration from the Messenger of Allah (peace be upon him), then all of them would gather for it and consensus (ijma’) would be established, and the truth is what their opinion would be; the truth is that upon which they established consensus.

From another chain, ‘Awwam bin Hawshab has also mentioned similarly.

Wahb bin Amr Jumahi narrated that the Prophet (peace be upon him) said: "Do not be hasty before the calamity descends. If you do not hasten before its descent, then the Muslims will not be relieved from it as long as there remains among them a person who, when he speaks, speaks with guidance, correctness, and truth. But if you act hastily in it, your opinions will differ and you will be seized in this way," and he gestured with his hands to the right and left.

Yahya bin Hamzah said that Sayyiduna Abu Salamah (may Allah be pleased with him) narrated to me that the Prophet (peace and blessings be upon him) was asked about a matter which was neither in the Qur'an nor in the Hadith. The Prophet (peace and blessings be upon him) said: "The devout believers will contemplate about it."

It is narrated from Abdullah bin Awn, Qasim bin Muhammad said: You people ask about such matters regarding which we did not use to ask questions. And you people argue about such things regarding which we did not use to argue. You inquire about such things that I do not know what they are, and if I had known, it would not have been permissible for us to conceal them from you.

Sayyiduna Umar bin Al-Khattab (may Allah be pleased with him) said: Soon there will come people who will argue with you about the mutashabihat (ambiguous) verses of the Qur'an, so you should take hold of them with their hadiths, because the people of the Sunnah have a very good knowledge of the Book of Allah.
