851. hadíth
قَالَ رَسُولُ اَللَّهِ صَلَّى اَللَّهُ عَلَيْهِ وَ آلِهِ: "مَنْ أَعْتَقَ مُؤْمِناً أَعْتَقَ اَللَّهُ بِكُلِّ عُضْوٍ مِنْهُ عُضْواً مِنَ اَلنَّارِ وَ إِنْ كَانَتْ أُنْثَى أَعْتَقَ اَللَّهُ بِكُلِّ عُضْوَيْنِ مِنْهَا عُضْواً مِنَ اَلنَّارِ لِأَنَّ اَلْمَرْأَةَ بِنِصْفِ اَلرَّجُلِ".
The Messenger of Allah (swt), peace be upon him and his family, said: "Whoever frees a believing slave, Allah (swt) will free a limb of his from the Fire for every limb of the slave. And if it is a female slave, Allah (swt) will free two limbs of his for every limb of hers from the Fire, because a woman is equal to half of a man."
