Is prayer permissible for the uncircumcised?

The prayer of the uncircumcised is valid if he removes the impurity; otherwise, his prayer is not valid unless he is unable to be circumcised. Circumcision is obligatory for the able-bodied adult Muslim, and it is a confirmed Sunnah, and a duty according to Ash-Shafi'i and Ahmad. The assessment of harm that prevents circumcision is referred to trustworthy doctors.
