I have read in many places that circumcision hasn't proven to be any helpful to our health and no advantages of it have been found.
Why are we required to get circumcised when we are born?
Are there any Hadith regarding this ruling?
Allah's apostle (pbuh) considered circumcision as Fitra of Prophets in the following Hadith and many other similar Ahadith.
Narrated Abu Huraira: The Prophet said "Five things are in accordance with Al Fitra (i.e. the tradition of prophets): to be circumcised, to shave the pelvic region, to pull out the hair of the armpits, to cut short the moustaches, and to clip the nails.' (Al-Bukhari Volume 8: Book 74: Hadith 312)
It is therefore evident that it was a tradition all Prophets followed.
Exclusively, we get the proof of the circumcision of Prophet Ibraheem (pbuh) in the Ahadith.
Narrated by Abu Huraira: Allah's Apostle said, "Abraham did his circumcision with an adze at the age of eighty." (Al-Bukhari : Volume 4 : Book 55 : Hadith 575)
This is why circumcision is considered as Sunnath-al-Ibrahimi (The Sunnah of Prophet Ibraheem[pbuh]).
Coming to the benefits of Circumcision, let us go through the following facts:
Infection or inflammation of the foreskin affects about 10% - 14% of uncircumcised boys.
urinary tract infections occur in about 1 in 100 uncircumcised boys in the first year of life, and 1 in 1,000 in circumcised boys. There is also an increased risk of inflammation and infections of the foreskin and glans in uncircumcised males.
Circumcision brings down the chances of catching genital ulcerative diseases.
Penile cancer is a risk for uncircumcised men. One male in 100,000 gets this malignancy and it is invariably an uncircumcised male.
A Kaiser Permanente HMO study found that uncircumcised infants are 10 times more likely to get kidney infections and urinary tract infections, especially in their first year of life.
Most importantly, the biggest health benefit conferred by circumcision is that it helps bring down the chances of contracting the dreaded HIV virus. Not only this, circumcised males carrying the AIDS virus are less likely to transmit it to their female partners.
It has been proven a myth that boys who are circumcised are less likely to contract HIV. Science has shown more complications in circumcision. Just look at the science behind the beneficial uses of the foreskin in intercourse. Why remove something Allah has created, thereby altering His creation? Shaitan is quoted in the Quran as saying:
"And most certainly I will lead them astray and excite in them vain desires, and bid them so that they shall slit the ears of the cattle, and most certainly I will bid them so that 'they shall alter Allah's creation'; and whoever takes the Shaitan for a guardian rather than Allah he indeed shall suffer a manifest loss. [4:119]
Finally, let us not forget that it is only Abu Hurairah who promotes circumcision, the same man that is reported by scholars to have gone to a mountain to learn the Talmud from a Jew. This is why we find contradictions in his ahadith eg. days of creation, women from adam's rib, etc all of which do not agree with the Quran. The Quran mentions the guarding of private parts and covering them, but NOWHERE for men to cut them. The Quran also does not mention Abraham's circumcision, as such is a Judeo-Christian fabrication inserted into the Old Testament along with other fabricated stories of Prophets who commit zina, incest, etc.
Circumcision is actually a pagan ritual and was promoted by elites, an offering to fake fertility gods. Now how is that for Islam?
He (shaitan) gives them promises and excites vain desires in them; and the Shaitan does not promise them but to deceive. [4:120]
