Most of such injunctions cannot be realized by people's aspirations, nor can they be comprehended by their reason. Among them is enjoining them to sacrifice themselves for the sake of achieving His Pleasure, Glorified and Exalted is He, and to spend all wealth, influence, and possessions in the process.
So you find them once in the depth of dungeons, or exiled, or deported, all the time suffering from apprehension and hardship, remaining against their wish silent as they are being verbally abused. This continued till they met their death. What savoured all of this for them was their being informed beforehand by their greatest grandfather (S), who was told by divine inspiration, of the merits and the interests whereby the Islamic nation is served.
Had they not been thus determined to offer such sacrifices, the creed would have been terribly distorted and misguidance would have crept therein. They found themselves submitting to that with which Allah had acquainted them of His secrets. He acquainted them with the great significance with Him, the most Exalted and Praised One that He is, despite the various degrees of sacrifice they had to offer.
The Almighty ordered some of them to withhold and not to fight or to be involved in jihad while ordering others to accept to be killed and yet others to accept to be poisoned. The mystery in such variation of obligation was due to what He, Glory to Him, saw of the interests according to their relevant time. Their bracing their death and taking poison was never due to their ignorance of what an oppressive ruler was doing to them. Rather, they were quite sure about it.
They knew of their killer and his method of killing, and even of the day and time, seeking submission to the Command of their Lord, the most Exalted One, and surrendering to the divine judgment in their regard. They are, in so doing, only carrying out all the orders they had received from the Master, Praise to Him, be they obligations or recommendations.
Reason determines that a slave must obey his master and not do anything forbidden without inquiring about the interest, or the lack thereof, that necessitated it. But if the Master is wise in everything He does, according to the verse saying, “He is not asked about what He does while they are,” (Qur’an, Sura al-Anbiyah, 21:23). obedience to Him ought to be unconditional, without questioning the reasons behind His orders.
It is this suggested view that the critics from among renowned scholars have endorsed.
