Q. Does the inserting of ones finger in one’s anus to clean oneself in the toilet whilst fasting break the fast?
A. The fast will not break by inserting a finger in the anus whilst cleaning oneself of impurities in the toilet. The fast will only break if a wet finger is inserted in the rectum whilst fasting knowingly or unknowingly.
In such a case, only a Qadha of that fast will have to be kept. (Fataawa Mahmoodiyyah 10/142)
