This image is a very good evidence that Circumcision has nothing to do with Islam. It is an old Egyptian custom some 1000s of years before Islam.
OK, if any one interested,....
According to Quran, the holiest of all books according to Islam. Allah is the best of creators. So Circumcision if you discard all the hadeaths that encourage or endorse MGM, the quran certainly states that Allah have exquisitely created man in the best form (got it? best form, which means no more snip snip, no more cutting, no more adjustments.... he was created by the all knowing best of the best creators). The following are the most well known verses from the Quran that explains that.
The best verse I like on the subject is the last on down there. Iblis (not our Kaffirist of course!) is actually challenging Allah and tells him that he will make people disobey Allah and change his creation. So in my humble opinion those who mutilate and change their children bodies permanently (remember that cutting off their nails or hair is not changing creation, these are temporarily cleaning measures that will grow back in several days).
لَقَدْ خَلَقْنَا الْإِنسَانَ فِي أَحْسَنِ تَقْوِيمٍ ﴿٤﴾
Certainly We created man in the best make
ثُمَّ خَلَقْنَا النُّطْفَةَ عَلَقَةً فَخَلَقْنَا الْعَلَقَةَ مُضْغَةً فَخَلَقْنَا الْمُضْغَةَ عِظَامًا فَكَسَوْنَا الْعِظَامَ لَحْمًا ثُمَّ أَنشَأْنَاهُ خَلْقًا آخَرَ ۚ فَتَبَارَكَ اللَّهُ أَحْسَنُ الْخَالِقِينَ ﴿١٤﴾
Then We made the seed a clot, then We made the clot a lump of flesh, then We made (in) the lump of flesh bones, then We clothed the bones with flesh, then We caused it to grow into another creation, so blessed be Allah, the best of the creators
أَتَدْعُونَ بَعْلًا وَتَذَرُونَ أَحْسَنَ الْخَالِقِينَ ﴿١٢٥﴾
What! do you call upon Ba'l and forsake the best of the creators
وَلَأُضِلَّنَّهُمْ وَلَأُمَنِّيَنَّهُمْ وَلَآمُرَنَّهُمْ فَلَيُبَتِّكُنَّ آذَانَ الْأَنْعَامِ وَلَآمُرَنَّهُمْ فَلَيُغَيِّرُنَّ خَلْقَ اللَّهِ ۚ وَمَن يَتَّخِذِ الشَّيْطَانَ وَلِيًّا مِّن دُونِ اللَّهِ فَقَدْ خَسِرَ خُسْرَانًا مُّبِينًا ﴿١١٩﴾
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.
