If Allah made man the best of his creation, then why did he create man with excessive foreskin on his penis? Since Circumcision is Wajib, what is the purpose of the foreskin?

Allah Almighty stated that humans are an honorable creation, and they are better than other creations such as the animals and plants. The excessive foreskin that needs to be removed is as equal as the sperm which the human being was made through and the blood that is within the human. Along with urine and waste that the human produces. The human is full of negativeness, but compared to other animals, he is more honorable as mentioned in the Holy Quran: “We have honored the children of Adam and preferred them over much from what we have created”. However, in the eyes of Allah Almighty, the best human being is the most faithful of them.
