Abu Dharr said he asked the Prophet what action was most excellent, and he replied, "Faith in God and jihad in His path." He then asked which slaves were most excellent ¹ and he replied. “Those whose price is highest and who are held in most esteem by their people." He asked what he should do if unable to act accordingly ² and he replied, "You should assist a workman, or work for one who is unskilled." He asked what he should do if unable to act accordingly and he replied, "Do no harm to others ³ for that is sadaqa you bestow on yourself." Bukhari and Muslim. 1. i.e. for the purpose of emancipating them. 2. The Arabic is fa-in lam af'al which is somewhat vague. It most probably means he is asking what he should do if unable to emancipate a slave of such quality. 3. This is an accepted meaning of the Arabic tada'u ‘un-nas min ash-sharr. Another possible meaning is to leave people alone because of their evil.
