let’s start from the beginning again and answer the original questions one by one.
- yes, muslims offer sacrifice to Allah and there are various times and situations where this is done.
the main sacrifice that most know about is the sacrifice that takes place on the day of 'eid al-adhaa (pronounced ad-haa), which is at the end of the hajj (pilgrimage to mecca). contrary to what my brother joseph mentioned of it being on a nation-wide level, the sacrifice done here is a personal sacrifice done by pilgrims as a ritual of hajj. the only thing that makes this a sacrifice on a nation wide level is the timing and the sheer number of pilgrims performing this act. there is debate and discussion regarding the obligation of sacrificing on this day for those who are not taking part in the hajj, thus, to say that this is a nation-wide sacrifice is not entirely correct.
another sacrifice that muslims offer is the sacrifice done when a child is born. this is called the 'aqeeqah or the naseekah. when a child is born, it is legislated that the parents slaughter a lamb or sheep on behalf of the child as a sacrifice to Allah; one for a girl and two for a boy. the sunnah is for this to be done on the seventh day after the birth of the child, or any day after that. (this is also the day that the male child is to be circumsized).
there are also various other instances where sacrifice is legislated as a means of “kafaarah” - expiation or atonement. one such instance is violating the conditions for ihraam (the state ritual consecration for hajj). among these violations are: intentionally removing hair or nails, having sexual relations with your spouse, hunting game, and others.
- sacrifice is offerred by slaughtering an animal from the various types of cattle and livestock. they are no longer slaughtered upon stone altars as this has been prohibited in the Quran, nor is there any special place such as a temple or its like required for it. there are certain conditions for sacrificing, which i’m sure you could find if you did a search on islam-qa.com. to my knowledge, the sacrifice can be performed by just about anyone. i’ll have to check on this to make sure, but i don’t know of any restrictions for who can and cannot do it. it is also generally allowed for sacrifices to be done on behalf of others - there might be some things restricting this, but i’ll have to check on that too.
as for your new questions:
- i’m not aware of any “view” held by muslims or islam concerning the old jewish temples, so i can’t comment on this.
- probably not, since there are no specific legislations for where sacrifices must performed. there is also a general prohibition from taking other religions’ places of worship as our own (although there are some exceptions to this, which i won’t get into here).
5 & 6. nothing has been mentioned in islamic scriptures regarding this command is from the corruptions of their texts or not, nor has anything been mentioned regarding your other questions (to my knowledge) thus no muslim can really comment on it.
