Here is somethin on using opinions instead of hearing and obeying. Hope it is helpful.
“And who can be better in religion than one who submits his face (himself) to Allah (i.e. follows Allah’s Religion );” Suratun-Nisa 4:125
And one who adopts the saying of Allah flees away from using his own ‘Aql (intellect) and from innovation.
When the Messenger of Allah was not authorized to introduce in this religion from his own intellect, then who else is there who claims such a right.
History and Experience have proven that those who have adopted a way of using their own intellect instead of the pure way of following (the Qur’an and Sunnah) have deviated. And not only did they misguide themselves but they became the cause of abasement of many others and after blackening their records of deeds they departed from this world.
In this short introduction we do not want to give a lengthy argument or else many examples could be given to prove this point, however we will suffice with one example.
In this ummah, the first sect which deviated on the basis of using ones intellect and opinion is known by the name of “Qadariyyah”. With regards to Qadr, instead of accepting the Shar’iah rulings apparently, these people started thinking about it using their own intellect. The more they thought, deeper they got into their errors, up until some of the impatient elements amongst them even rejected the Qadr. In contrast, with regards to it, some of them declared man to be totally helpless. For them the worship and sins of Allah’s slaves are equal.
The Messenger of Allah said about them:
Such people (i.e. the Qadariyyah) are the majoos of this Ummah. (Abu Dawood)
Once in front of His companion, Abdullah bin Umar (radiallaahuanhu) Qadariyyah was mentioned, so he said:
“If I come across these people then I would break their necks.”
There is no shortage of such people who preach intelligence and opinion in our times where mischief is abundant. Many issues are being understood by using ones own intellect and the result is nothing but misguidance and one of its examples is the issue of punishment in the Grave.
This issue is proven by evident injunctions from Qur’an and Sunnah. There is safety, peace and felicity only in Belief, certainty and Acceptance but many people are relentless in using their intellect and get entwined in this corrupt behavior and get misguided, rather fall into the pitch darkness of Kufr.
Because of this behavior of theirs, it is necessary that they reject the Shar’ee injunctions but in some cases they involve themselves into metaphysics and nature[2]. The filth of such people is a reason of many problems faced in the collective existence of this ummah.
People! The cure for this whimpering and restless nation is hidden only in the following of the Messenger(sallallaahu alaihi wasallam). The companions of the Messenger (saw) used to abstain from opinions in the Religion. Abu Bakr (radiallaahuanhu) used to say:
“If I say anything in this religion from my opinion then I do not have any refuge.”
This saying of Umar bin al-Khattab is famous:
“Beware of opinion in religion.”
