Jawaid Bhai, sorry for the delay in replying to your Post. Sent computer for repairs and still having issues.
Anyway, to understand the answer to your question on circumcision, you have to understand that the Qur’an like the Old and New Testaments of the Bible is a means of developing and understanding the natural laws of human life (adDeeni Haneefan) based on the natural laws of the heavens and the earth, which include that of the animal kingdom and that of the “millat of Ibrahim”.
Hence, in this context, circumcision is an option but not so homosexuality. Likewise, there is no restriction on polygamy as long as there is “justice”.
Hence, “judging by the Qur’an” implies using Qur’an in the context of God’s Work in the Signs and science of His Work in His creations and in the history of the deen that includes the revealed knowledge of the Old and New Testaments of the Bible and traditions due to them in the “millat of Ibrahim”.
This applies to the knowledge of salaat as much it applies to the knowledge of the creation. For example, the Qur’an does not tell us when God created the seasons. The Bible tells us in Genesis 1:14-19 that He created it when He created light in the darkness of night through moon and stars and created the seven firmaments of the heaven.
Likewise, the Bible tells us that Jesus fell on his face and prayed. And, likewise, it is said that on Yom Kippur the Jews pray like the Muslims.
Hence, using Qur’an by ignoring God’s Work in the Signs and science of His creation and the history of the deen based on the “millat of Ibrahim” is not Islam.
Abraham did not reject his father’s religion because his father followed tradition. It was because he followed tradition that did not make sense.
On the other hand the descendents of Abraham followed tradition that made sense.
