1 عَنْ عَبْداللَّهِ بْنِ سِنَانٍ أَبِي عَبْداللَّه في حديث قَالَ يَا ابْنَ سِنَانٍ إِنَّ شَعْرَ الْمَرْأَةِ وَ عُذْرَتَهَا شَرِيكَانِ فِي الْجَمَالِ فَإِذَا ذُهِبَ بِأَحَدِهِمَا وَجَبَ لَهَا الْمَهْرُ كَامِلًا
📚 Al-Tahdhib, Vol. 10, p. 262
Abdullah ibn Sinan said: Imam Sadiq (peace be upon him) said in a hadith: 'O son of Sinan! A woman's hair and her virginity are two partners in her beauty and charm. So if one of these two is destroyed, the full dowry will be for that woman!'
2 عَنِ الْحَلَبِيِ عَنْ أَبِي عَبْداللَّه قَالَ: لَيْسَ عَلَى النِّسَاءِ حَلْقٌ وَ عَلَيْهِنَّ التَّقْصِيرُ الْحَدِيثَ.
📚 Tahdhib, Vol. 5, p. 390
Imam Sadiq (peace be upon him) said: 'It is not for women (in Hajj and Umrah) to shave their heads, and they are responsible for shortening their hair!'
3 عَنْ جَابِرٍ عَنْ أَبِي جَعْفَر قَالَ: قَالَ رَسُولُ اللَّه فِي حَدِيثٍ لَعَنَ اللَّهُ الْمُتَشَبِّهِينَ مِنَ الرِّجَالِ بِالنِّسَاءِ وَ الْمُتَشَبِّهَاتِ مِنَ النِّسَاءِ بِالرِّجَالِ...
📚 Al-Kafi, Vol. 8, p. 69
Imam Baqir (peace be upon him) said: The Messenger of Allah (peace be upon him and his family) said in a hadith: 'Allah has cursed the men who imitate women and the women who imitate men!'
4 عَنْ جَابِرِ بْنِ يَزِيدَ الْجُعْفِيِّ قَالَ سَمِعْتُ أَبَا جَعْفَرٍ مُحَمَّدَ بْنَ عَلِيٍّ الْبَاقِر يَقُولُ لَيْسَ عَلَى النِّسَاءِ أَذَانٌ وَ لَا إِقَامَةٌ...وَ لَا الْحَلْقُ وَ إِنَّمَا يُقَصِّرْنَ مِنْ شُعُورِهِنَّ.... وَ لَا يَجُوزُ لَهَا أَنْ تَتَشَبَّهَ بِالرِّجَالِ لِأَنَّ رَسُولَ اللَّهِ لَعَنَ الْمُتَشَبِّهِينَ مِنَ الرِّجَالِ بِالنِّسَاءِ وَ لَعَنَ الْمُتَشَبِّهَاتِ مِنَ النِّسَاءِ بِالرِّجَالِ
📚 Khisal, p. 585
Jabir said: I heard Imam Baqir (peace be upon him) say: 'There is no adhan and iqama for women... and it is not for them to shave their heads (in Hajj and Umrah), and indeed they shorten their hair... and it is not permissible for her to imitate men, because the Messenger of Allah (peace be upon him and his family) cursed the men who imitate women and the women who imitate men!'
5 عَنْ عَلِيٍّ قَالَ: أَقْبَلَتِ امْرَأَةٌ إِلَى رَسُولِ اللَّهِ فَقَالَتْ يَا رَسُولَ اللَّهِ إِنَّ لِي زَوْجاً بِهِ عَلَيَّ غِلْظَةٌ وَ إِنِّي صَنَعْتُ شَيْئاً لِأَعْطِفَهُ عَلَيَّ فَقَالَ رَسُولُ اللَّهِ أُفٍّ لَكِ كَفَرْتِ دِينَكِ لَعَنَتْكِ مَلَائِكَةُ السَّمَاءِ لَعَنَتْكِ مَلَائِكَةُ الْأَرْضِ فَصَامَتْ نَهَارَهَا وَ قَامَتْ لَيْلَهَا وَ لَبِسَتِ الْمُسُوحَ ثُمَّ حَلَقْتَ رَأْسَهَا فَبَلَغَ ذَلِكَ رَسُولَ اللَّهِ فَقَالَ إِنَّ حَلْقَ الرَّأْسِ لَا يُقْبَلُ مِنْهَا
📚 Ja'fariyat, p. 99
Ali (peace be upon him) said: A woman came to the Messenger of Allah (peace be upon him and his family) and said: 'O Messenger of Allah, I have a husband who was rough and harsh towards me, and I have done something to make him kind and affectionate towards me!'
The Messenger of Allah (peace be upon him and his family) said to her: 'Woe to you! You have been ungrateful and unthankful to your religion. The angels of the heavens have cursed you, the angels of the earth have cursed you!'
So the woman fasted during the day and prayed at night and wore rough clothes, and then she shaved her head (to be forgiven)!
This news reached the Messenger of Allah (peace be upon him and his family), so he said: 'Indeed, her shaving of the head will not be accepted from her!'
✅ According to the above narrations and others, a woman's hair is one of her beauties, and it is not permissible to shave it in any place, nor is it recommended. Even in Hajj and Umrah, shaving is not prescribed for them, and they are assigned the duty of shortening a small amount of their hair. Shaving hair is not accepted for a woman even for the sake of repentance, and in many narrations, women who imitate men have been cursed and condemned.
✅ Of course, in narrations, shaving the head of a newborn is mentioned as one of the traditions of the seventh day, and it includes both male and female newborns.
You can see some of the narrations about shaving the head of a newborn at the following link:
اللَّهُمَّ صَلِّ عَلَی مُحَمَّدٍ وَ آلِ مُحَمَّدٍ وَ عَجِّلْ لِوَلِیِّکَ الْفَرَجَ وَ الْعَافِیَةَ وَ النَّصْرَ
