The example of those who disbelieve and stubbornly follow the path of their fathers is like the example of the shepherd who shouts, calling to his animals that hear his voice, but do not understand what he says. They are deaf to hearing the truth so that it will benefit them, dumb as they are unable to speak about the truth, and blind to seeing it, and because of this they do not understand the guidance which you call them to.
And the example of those who disbelieve is as that of him who shouts to those (flock of sheep) that hear nothing but calls and cries. (They are) deaf, dumb and blind. So they do not understand (170)
The Polytheist imitates Other Polytheists
Allah states that if the disbelievers and polytheists are called to follow what Allah has revealed to His Messenger ﷺ and abandon the practices of misguidance and ignorance that they indulge in, they will say, "Rather. We shall follow what we found our fathers following," meaning, worshipping the idols and the false deities. Allah criticized their reasoning:
أَوَلَوْ كَانَ آبَاؤُهُمْ
((Would they do that!) even though their fathers), meaning, those whom they follow and whose practices they imitate, and:
لَا يَعْقِلُونَ شَيْئًا وَلَا يَهْتَدُونَ
(...did not understand anything nor were they guided?) meaning, they had no sound understanding or guidance. Ibn Ishaq reported that Ibn 'Abbas said that this was revealed about a group of Jews whom Allah's Messenger ﷺ called to Islam, but they refused, saying, "Rather, we shall follow what we found our forefathers following." So Allah revealed this Ayah (2:170) above."
The Disbeliever is just like an Animal
Allah then made a parable of the disbelievers, just as He said in another Ayah:
لِلَّذِينَ لَا يُؤْمِنُونَ بِالْآخِرَةِ مَثَلُ السَّوْءِ
(For those who believe not in the Hereafter is an evil description.)(16:60)
Similarly, Allah said here (2:171 above)
وَمَثَلُ الَّذِينَ كَفَرُوا
(And the example of those who disbelieve...) meaning, in their injustice, misguidance and ignorance, they are just like wandering animals, not understanding what they are told; if the shepherd heralds them or calls them to what benefits them, they would not understand what is actually being said to them, for they only hear unintelligible sounds. This is what is reported from Ibn 'Abbas, Abu Al-'Aliyah, Mujahid, 'Ikrimah, 'Ata', Al-Hasan, Qatadah, 'Ata' Al-Khurasani and Ar-Rabi' bin Anas.
صُمٌّ بُكْمٌ عُمْيٌ
(They are deaf, dumb, and blind.) means, they are deaf, as they do not hear the truth; mute, as they do not utter it; and blind, as they do not see or recognize its path and way.
فَهُمْ لَا يَعْقِلُونَ
(So they do not understand.) means, they do not comprehend or understand anything.
When these mushrik people were asked to follow the injunctions revealed by Allah through His Messenger, they refused to do so and insisted that they would rather follow the customary practice they had inherited from their fathers because, as they assumed, their models were divinely appointed to follow the way they adopted. Allah Almighty refutes this position of theirs by asking how could they go on following the ways of their fathers, under all conditions, to the exclusion of all other ways, even if their fathers did not understand much about the true faith, nor were they blessed with guidance given by their Lord?
In their lack of understanding, the verse says that the disbelievers resemble the scenario of a person shouting his call to an animal who hears nothing meaningful or significant except a bland cry. The disbelievers, in that state, do hear but not what is intended to correct them, so they are called 'deaf; and they are tight-lipped when it comes to accepting the truth, therefore, they are 'dumb'; and since they do not see their benefit or loss, they are 'blind'. Consequently, with their vital senses so dulled, they seem to understand nothing.
Comments on the nature of Taqlid:
No doubt, this verse (170) does censure the blind following of forefathers, but at the same time, it provides a rule and its attending conditions proving that following has its permissible aspect which has been indicated in لَا يَعْقِلُونَ (even though their forefathers used to understand nothing) and لَا يَهْتَدُونَ (nor had they been on the right path). It is from here that we find out that following the forefathers mentioned in the text of the Qur'an was censured because they lacked reason and guidance. 'Guidance' or the right path signifies injunctions revealed by Allah Almighty, openly and clearly, while ` aql عقل or reason stands for imperative guidance deduced by the great armed vision of Ijtihad اجتھاد from the recognized sources of Islamic Shari'ah.
Now we can see that following the model of those identified in the text cannot be permitted because they do not have a revealed set of laws from Allah, nor do they have the ability to deduce injunctions from the Word of Allah. There is a subtle hint here which we would do well to note. In case, we are satisfied that a certain ` alim عالِم has the perfect knowledge of the Qur'an and Sunnah and in the absence of a clear and direct instruction of the two sacred sources, he has the great expertise of a mujtahid مجتھد so that he can, by analogical deduction, arrive at rulings from the texts of the Qur'an and Sunnah - then. it is permissible to follow such mujtahid مجتھد alim عالِم . It does not mean that one has to obey 'his' injunctions and follow 'his person.' Instead, it means that one has to obey the injunctions of Allah alone to the total exclusion of others. But, since a direct and trustworthy knowledge of the injunctions of Allah (in all their ramifications) is not readily available to us due to our ignorance, we have to follow a mujtahid مجتھد alim عالِم in order to act in accordance with the injunctions of Allah Almighty.
From what has been said above, it becomes clear that those who hasten to quote verses of this nature against following the great mujtahid imams, are themselves unaware of the proven meaning of these verses.
In his comments on this verse, the great commentator, al-Qurtubi has said that the prohibition of following forefathers mentioned in this verse refers to. following them in false beliefs and deeds. The aspect of following correct beliefs and good deeds is not included here as it has been very clearly projected in Surah Yusuf in the words of Sayyidna Yusuf (علیہ السلام) :
إِنِّي تَرَكْتُ مِلَّةَ قَوْمٍ لَّا يُؤْمِنُونَ بِاللَّـهِ وَهُم بِالْآخِرَةِ هُمْ كَافِرُونَ ﴿37﴾ وَاتَّبَعْتُ مِلَّةَ آبَائِي إِبْرَاهِيمَ وَإِسْحَاقَ وَيَعْقُوبَ
I have disassociated myself from the community of people who do not believe in Allah and who deny the Hereafter and I have chosen to follow the community of my fathers, Ibrahim and Ishaq and Ya` qub. (12:37-38)
This is good enough to prove that following forefathers in what is false is forbidden while it is permissible, rather desirable, in what is true.
Al-Qurtubi has taken up the issue of following the mujtahid imams within his comments on this verse. He says:
تعلق قوم بھذہ الآیہ فی ذمً التقلید (الی) وھذا فی الباطل صحیح اما التقلید فی الحق فاصل من اصول الدین وعصمۃ من عصم المسلمین یلجأ اِلیھا الجاھل المقصرعن درک النظر
"Some people have quoted this verse to support their criticism against Taqlid (following). As far as following the false is concerned, this is correct. But, this has nothing to do with following what is true which is, in fact, a basic religious principle, and a great means of protecting the religion of Muslims in as much as one who does not have the ability to do Ijtihad must rely on 'following' in matters of religion." (volume 2, page 194)
Once an object, which is not God, is accepted as God as a result of man’s superstitious attitude, many other accompanying evils ensue. An animal may come to be regarded as possessing supernatural powers—something possessed only by God. That animal is then held to be a means of achieving proximity to God and is expected to be a source of blessings. In the next generation all these superstitious beliefs become firmly rooted in the human psyche and are upheld with great zeal and fervour as the sacred way of the forefathers. At this stage, people become resistant to any rational analysis of these superstitious beliefs. The situation deteriorates further with succeeding generations. People reach a level where they are totally unable to hear or understand any argument put forward to them. They act as if they have neither eyes nor ears to see and hear, nor brains to give thought to any argument presented to them.
