Shaqiq (bin Salamah) narrates that Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) said: "What will you do when you are surrounded by such tribulations in which the young will become old and the child will become a youth, and people will take these tribulations (innovations) as Sunnah, and when someone tries to change them, people will say: 'The Sunnah has been changed.' People asked: 'Abu Abdur Rahman! When will this happen?' He replied: 'When your reciters (scholars) will be many and jurists will be few, rulers will be many but trustworthy ones will be few, and deeds will be for the sake of the world instead of the Hereafter.'"

It is narrated from Alqamah that Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) said: What will you do during times of tribulation when in those tribulations the old will become elderly and the child will grow up? When something (an innovation) is abandoned in those tribulations, it will be said that a Sunnah has been abandoned. The people asked: When will that happen? He replied: When your scholars will perish and the ignorant will become numerous, there will be many reciters (of the Qur'an) but few jurists, many leaders but few trustworthy people, people will seek the world instead of working for the Hereafter, and other things will be learned instead of the religion.

Imam Awza'i, may Allah have mercy on him, said: I have been informed that it used to be said: Destruction is for the one who acquires jurisprudence in anything other than worship, and for those who make the sacred things lawful through doubts.

It is narrated from Masruq that Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) said: The year that will come upon you will be worse than the previous year. I do not mean that one year will be more fertile and lush than the other, nor do I mean that one ruler will be better than the other. What I mean is that your scholars, the righteous and the jurists, will depart, and you will not find anyone to succeed them, and there will come people who will measure matters and affairs according to their own opinions.

Imam Muhammad bin Sirin, may Allah have mercy on him, said: The first to use analogy (qiyas) was Iblis, and it was due to analogy that the sun and the moon were worshipped.

It is narrated from Matar (al-Warraq) that Hasan (may Allah have mercy on him) recited this noble verse: «﴿خَلَقْتَنِي مِنْ نَارٍ وَخَلَقْتَهُ مِنْ طِينٍ﴾» [الأعراف: 12/7] and said, "Iblis made analogy (qiyas), and he was the first to make analogy."

Masruq said: I fear making analogies and that my foot may slip. (That is, I may fall into misguidance.)

Imam Sha’bi (may Allah have mercy on him) said: By Allah, if you make analogy (qiyas) the standard, you will declare the lawful as unlawful and the unlawful as lawful.

Imam Amir Sha'bi, may Allah have mercy on him, used to say: In my view, the most detestable thing to say is "What is your opinion?" If a man asks his companion, "What do you think?" and he replies, "What is your opinion?" And Amir did not engage in analogical reasoning (qiyas).

Zabraqan said: Abu Wa'il forbade me from sitting with the people of opinion (those who rely on opinion and analogy).
