thoroughly means swirling the water so that it reaches every part of the mouth, and—when inhaling water—drawing it up to the uppermost part of the nose.
Fourth: another sunnah of ablution is to run water through a thick beard until it reaches the skin beneath, and to work the water between the fingers and toes.
Fifth: beginning with the right—washing the right hand and foot before the left.
Sixth: increasing the wash from once to two or three times for the face, hands, and feet.
These, then, are the conditions, obligatory acts, and recommended practices of ablution. It befits you to learn them and to apply them whenever you perform ablution, so that your purification is complete and compliant with the law, and thus you earn the reward.
We ask Allah to grant us and you further beneficial knowledge and righteous deeds.
