Is it obligatory to repeatedly attempt conception via ICSI, or is that considered a challenge to the will of Allah, taking into account the difficulty of natural conception, the death of the previous child, Allah's saying: "And perhaps you love a thing and it is bad for you," and the Prophet's saying: "Seek treatment"?

There is no contradiction between taking means and being content with Allah's decree and destiny, for Allah created the cause and the effect. Relying solely on means is polytheism (shirk), and completely abandoning them is a flaw in the Sharia. Rather, reliance and desire should be directed towards Allah. Allah decrees whatever means He wishes, and He has made a cause for everything. Thus, His wisdom necessitated that the effect cannot be achieved except through what He made its cause. Taking means to conceive and have a child is not an objection to Allah's will; rather, it is religiously commanded because it is among the objectives of the Sharia. Using the verse: "And perhaps you hate a thing and it is good for you" [Quran 2:216] as an argument for not taking means is incorrect. The Prophet, peace be upon him, said: "Be keen on what benefits you, seek help from Allah, and do not lose heart. And if anything befalls you, do not say, 'If only I had done such and such,' but rather say, 'Allah has decreed and what He willed He has done.'" This encourages taking means and not losing heart, and after a calamity occurs, one says, "Allah has decreed and what He willed He has done." The wife is not obligated to undergo procedures to conceive a child unless her husband requests it.
