What is the ruling on accidentally pulling out a single hair during الإحرام?

If a single hair falls out unintentionally — such as during الوضوء or while scratching — there is no sin and no فدية is required. الشيخ ابن باز stated: 'If hairs fall out without intention during washing or combing, there is no harm.' The prohibition is on deliberately cutting or removing hair. If a الحاج deliberately removes three or more hairs, he must offer فدية (the choice between fasting three days, feeding six poor people, or sacrificing a sheep).
