Well, the key tenets of beliefs and the legal outline laid down in the revealed texts are essentially immutable, per what a Muslim is meant to subscribe to. If this core idea is not there, that is logically equivalent to not subscribing to the religion (whoever wants to change whatever at wherever renders <i>any</i> belief fundamentally void, let alone what one believes to be God&#x27;s guidance). But the jurisprudential framework (&#x27;usul al-fiqh&#x27;) encompasses the principles to formulate specific course of action according to the immutable legislative guideline (formulated from authentic texts) in the specific circumstances. An example, harming oneself is prohibited in the text, so smoking has the ruling of being impermissible as its harms are largely known now while earlier academics used to deem it disliked based on another textual principle.
In short, there are constants and there are variables; without any constants, it all becomes tendentious whimsy.<p>The ideas related to the roles, responsibilities and  respectability of the individuals are different in the Islamic creed. Yes, a woman gets half from her father (her husband owes her, legally), and she is exempt from the basic responsibility to become the breadwinner. Any Muslim is meant to respect and care for his&#x2F;her mother more than the father. Historically many Muslim women were scholars (<a href="https:&#x2F;&#x2F;archive.org&#x2F;download&#x2F;AlMuhaddithat&#x2F;al%20-%20Muhaddithat.pdf" rel="nofollow">https:&#x2F;&#x2F;archive.org&#x2F;download&#x2F;AlMuhaddithat&#x2F;al%20-%20Muhaddit...</a>) and rich (in the old Muslim heritage, many of the large endowments for public welfare are known to be from women). Besides, a merely demographically Muslim territory may not embody much of the Islamic ideals though.<p>In the other part, I was referring to the epistemological basis regarding the concepts of triumph&#x2F;progress; in particular, in a framework where basically, &quot;we are from nowhere, we are going to nowhere and we are here for nothing&quot;, nothing really signifies anything.<p>Thanks.
