Chapter: On the Siwāk (tooth-stick) and Other Grooming Sunnahs
• It is recommended to use the siwāk by passing it crosswise with the left hand, employing a pliant twig such as that of the arāk tree. It is disliked for a fasting person after the sun has passed its zenith. Its recommendation is especially emphasized when performing the prayer, upon waking, and whenever the mouth’s odor changes. One begins with the right side of the mouth.
• One should apply oil every other day (1) and put on kohl an odd number of strokes.
• Circumcision is obligatory for both males and females upon reaching puberty, provided one does not fear serious harm; performing it in early childhood is preferable.

• Perform qazaʿ (partially shaving the head and leaving portions unshorn) (2),
• Pierce a boy’s ear,
• Pluck out grey hairs, or
• Dye the hair jet-black.
