Are urine droplets that splash back from the toilet or directly hit clothes or the body during urination, as well as water droplets that splash back from washing impurity before purifying the hand, excused as minor impurities, and what is meant by the excused amount of a dirham in centimeters, and are small specks of feces on underwear excused, and must ablution be repeated when in doubt after completing it, and how can one be certain of the transfer of impurity from outer clothing to inner clothing or the body, and is prayer accepted when there is a mistaken judgment regarding impurity, and are these questions considered obsessive whispering (waswasah)?

First: The pardoned impurity is a minor impurity, the estimation of which is left to common practice. It is considered minor if there is doubt, until it is certain that it is abundant. Prayer with it is valid.

Second: Among those who estimated the pardoned impurity to be the size of a dirham, they differed in its estimation. Some said it is the size of the upper joint of the pinky finger, others said it is the size of that finger if it were folded, and still others said it is the size of a wound's opening.

Third: If a minor impurity is found, it is more cautious to wash it if it is seen and its location is known, out of consideration for the opinion of those who do not pardon impurity, even if minor.

Fourth: When in doubt about washing a limb after completing ablution, the doubt should not be heeded, and there is no need to repeat the ablution. The same applies to doubting purity after finishing it.

Fifth: If an impurity affects the outer clothing and you doubt its reaching the inner clothing, the doubt should not be heeded, because the inner clothing is originally pure.
