alkafi-4140Vol. 3, p. 76

لَا يَكُونُ الْقُرْءُ فِي أَقَلَّ مِنْ عَشَرَةِ أَيَّامٍ فَمَا زَادَ أَقَلُّ مَا يَكُونُ عَشَرَةٌ مِنْ حِينِ تَطْهُرُ إِلَى أَنْ تَرَى الدَّمَ.

“Abu Ja‘far (a.s.), has said, ‘The minimum Hayd (menses) free period is ten days, that is, the time from the end of one period of Hayd (menses) to the beginning of the second one.’”

أَدْنَى الطُّهْرِ عَشَرَةُ أَيَّامٍ وَ ذَلِكَ أَنَّ الْمَرْأَةَ أَوَّلَ مَا تَحِيضُ رُبَّمَا كَانَتْ كَثِيرَةَ الدَّمِ فَيَكُونُ حَيْضُهَا عَشَرَةَ أَيَّامٍ فَلَا تَزَالُ كُلَّمَا كَبِرَتْ نَقَصَتْ حَتَّى تَرْجِعَ إِلَى ثَلَاثَةِ أَيَّامٍ فَإِذَا رَجَعَتْ إِلَى ثَلَاثَةِ أَيَّامٍ ارْتَفَعَ حَيْضُهَا وَ لَا يَكُونُ أَقَلَّ مِنْ ثَلَاثَةِ أَيَّامٍ فَإِذَا رَأَتِ الْمَرْأَةُ الدَّمَ فِي أَيَّامِ حَيْضِهَا تَرَكَتِ الصَّ

The minimum duration of Hayd (menses) free period is ten days. This is because when a woman experiences Hayd (menses) it is of a greater amount and it takes ten days. It continues and as time passes and she grows older, the duration of her Hayd (menses) reduces to three days. In this condition it does not go higher and
