1009. hadíth
وَ قَالَ عَلَيْهِ اَلسَّلاَمُ: "لاَ بَأْسَ بِكَسْبِ اَلْمَاشِطَةِ إِذَا لَمْ تُشَارِطْ وَ قَبِلَتْ مَا تُعْطَى وَ لاَ تَصِلُ شَعْرَ اَلْمَرْأَةِ بِشَعْرِ اِمْرَأَةٍ غَيْرِهَا فَأَمَّا شَعْرُ اَلْمَعْزِ فَلاَ بَأْسَ بِأَنْ يُوصَلَ بِشَعْرِ اَلْمَرْأَةِ وَ لاَ بَأْسَ بِكَسْبِ اَلنَّائِحَةِ إِذَا قَالَتْ صِدْقاً ".
Imam (a.s) said: "There is no harm in the earnings of a hairdresser if she does not stipulate a specific payment and accepts what is given to her. However, she should not attach the hair of one woman to the hair of another woman. As for the hair of goats, there is no harm in attaching it to a woman's hair. Also, there is no harm in the earnings of a mourner if she speaks the truth."
