If you then intend to perform the ritual ablution (wudu’), you may before that begin with brushing the teeth with the miswak (a stick used for cleansing the teeth), because it cleanse the mouth, removes phlegm, strengthens the memory, increases the good deeds, and pleases the Exalted Lord. A two-unit prayer that is preceded by cleansing the teeth is more favorable than seventy-unit prayer without it. If a miswak is not available, it is acceptably sufficient to use one’s finger (for cleansing the teeth).
