What practice does the qu'ran allow that many other religions prohibit?

The correct answer is polygamy.

Explanation:

According to Islamic law, men can have up to four wives at one time.

Polygamy, or the practice of being married to multiple wives, is one of the practices that Qur'an allows and other religions prohibit.

Its main purpose was to provide care to all widows and orphans in a society in which women did not have any rights to be independent or to earn some money. Qur'an allows polygamy if all wives are treated justly.

This practice is neither mandatory but merely permitted, although it is strictly forbidden in another religion, for example, Christianity, Hinduism, etc.

it was certainly a debatable decision, mainly because it was based primarily on political - and not on legal or social - views. since the congress at that time was led by members of the republican party, and the territory that the tribes wanted to turn into an exclusively indian state was predominantly democratic, the proposal (as expressed in the constitution) did not succeed, but the constitution itself proved to be of crucial importance in the creation of the state of oklahoma, and, most importantly, it guaranteed the involvement of representatives of the indian tribes in the government of the future joint state.  

as a member of congress, i would have voted to ratify the constitution, or at least to have it tabled. ignoring it was an interested and partial decision.
