If a man or a woman embraces Islam after reaching thirty or forty years of age, should they be circumcised? Is it permissible for the uncircumcised man to be an Imam (the one who leads congregational prayer)?
All Praise be to Allah Alone and peace and blessings be upon His Messenger, his family and Companions.
Circumcision is one of Sunan-ul-Fitrah (Islamic practices of personal hygiene) for both men and women. If a person does not do it after they grow up, they are not to be blamed. As for the uncircumcised man, he can be an Imam in Salah (Prayer). (Part No. 5; Page No. 118) May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
