I am past menopause, or I have never had periods. How long is my iddah after a divorce?

(وَالصَّغِيرَةُ) لَوْ حَاضَتْ بَعْدَ تَمَامِ الْأَشْهُرِ (لَا) تَسْتَأْنِفُ (إلَّا إذَا حَاضَتْ فِي أَثْنَائِهَا) فَتَسْتَأْنِفُ بِالْحَيْضِ (كَمَا تَسْتَأْنِفُ) الْعِدَّةَ (بِالشُّهُورِ مَنْ حَاضَتْ حَيْضَةً) ، أَوْ ثِنْتَيْنِ (ثُمَّ أَيِسَتْ)

A young girl who menstruates after the months are complete does not start again, unless she menstruates during them, in which case she starts again with menstruations; just as a woman who menstruated once or twice and then passed menstruation starts the iddah again in months.

أَمَّا إذَا عَرَفَتْ أَنَّ ارْتِفَاعَ الْحَيْضِ بِعَارِضٍ؛ مِنْ مَرَضٍ، أَوْ نِفَاسٍ، أَوْ رَضَاعٍ، فَإِنَّهَا تَنْتَظِرُ زَوَالَ الْعَارِضِ، وَعَوْدَ الدَّمِ وَإِنْ طَالَ، إلَّا أَنْ تَصِيرَ فِي سِنِّ الْإِيَاسِ، وَقَدْ ذَكَرْنَاهُ. فَعِنْدَ ذَلِكَ تَعْتَدَّ عِدَّةَ الْآيِسَاتِ

If she knows that her menstruation stopped because of something that came up — illness, postnatal bleeding or breastfeeding — she waits for it to pass and for the blood to return, however long it takes, unless she reaches the age of menopause, as we mentioned; then she observes the iddah of women past menstruation.

إذَا طَلَّقَ امْرَأَتَهُ، وَهِيَ مِنْ ذَوَاتِ الْأَقْرَاءِ، فَلَمْ تَرَ الْحَيْضَ فِي عَادَتِهَا، وَلَمْ تَدْرِ مَا رَفَعَهُ، فَإِنَّهَا تَعْتَدُّ سَنَةً؛ تِسْعَةَ أَشْهُرٍ مِنْهَا تَتَرَبَّصُ فِيهَا لِتَعْلَمَ بَرَاءَةَ رَحِمِهَا؛ لِأَنَّ هَذِهِ الْمُدَّةَ هِيَ غَالِبُ مُدَّةُ الْحَمْلِ، فَإِذَا لَمْ يَبْنِ الْحَمْلُ فِيهَا، عُلِمَ بَرَاءَةُ الرَّحِمِ ظَاهِرًا، فَتَعْتَدَّ بَعْدَ ذَلِكَ عِدَّةَ الْآيِسَاتِ، ثَلَاثَةَ أَشْهُرٍ. هَذَا قَوْلُ عُمَرَ - رَضِيَ اللَّهُ عَنْهُ -، قَالَ الشَّافِعِيُّ هَذَا قَضَاءُ عُمَرَ بَيْنَ الْمُهَاجِرِينَ وَالْأَنْصَارِ، لَا يُنْكِرُهُ مِنْهُمْ مُنْكِرٌ عَلِمْنَاهُ. وَبِهِ قَالَ مَالِكٌ، وَالشَّافِعِيُّ فِي أَحَدِ قَوْلَيْهِ … وَقَالَ فِي الْجَدِيدِ: تَكُونُ فِي عِدَّةٍ أَبَدًا، حَتَّى تَحِيضَ، أَوْ تَبْلُغَ سِنَّ الْإِيَاسِ، تَعْتَدُّ حِينَئِذٍ بِثَلَاثَةِ أَشْهُرٍ

If a man divorces his wife while she is one who menstruates, and she does not see her period at its usual time and does not know what stopped it, she observes a year: nine months in which she waits to know her womb is empty, because that is the usual length of pregnancy; if no pregnancy appears, the womb is outwardly known to be empty, and she then observes the iddah of women past menstruation, three months. This is the ruling of ʿUmar; al-Shāfiʿī said it was ʿUmar's judgment among the Muhājirūn and Anṣār, and he knew of no one who objected. Mālik held it, and al-Shāfiʿī in one of his two views. Al-Shāfiʿī said in the new view: she remains in iddah until she menstruates or reaches the age of menopause, and then observes three months.

(وَ) الْعِدَّةُ (فِي) حَقِّ (مَنْ لَمْ تَحِضْ) حُرَّةً أَمْ أُمَّ وَلَدٍ (لِصِغَرٍ) بِأَنْ لَمْ تَبْلُغْ تِسْعًا (أَوْ كِبَرٍ)

The iddah of one who does not menstruate, because she is young (has not reached nine years) or old…

(ثَلَاثَةُ أَشْهُرٍ) بِالْأَهِلَّةِ لَوْ فِي الْغُرَّةِ وَإِلَّا فَبِالْأَيَّامِ بَحْرٌ وَغَيْرُهُ (إنْ وُطِئَتْ) فِي الْكُلِّ وَلَوْ حُكْمًا كَالْخَلْوَةِ وَلَوْ فَاسِدَةً كَمَا مَرَّ

…is three months: by the crescents if the divorce was at the start of the month, and otherwise by days — if intercourse took place, in all of these cases, even constructively, such as seclusion (khalwah), even an invalid one, as stated before.

كَعِدَّةِ مَنْ لَمْ تَرَ الْحَيْضَ) لِصِغَرٍ، وَهِيَ مُطِيقَةٌ أَوْ لِكَوْنِهَا لَمْ تَرَهُ أَصْلًا. (وَ) عِدَّةُ (الْيَائِسَةِ) مِنْ الْحَيْضِ فَإِنَّهَا ثَلَاثَةُ أَشْهُرٍ وَقَوْلُهُ: (وَلَوْ بِرِقٍّ) مُبَالَغَةٌ فِي قَوْلِهِ: وَإِنْ لَمْ تُمَيِّزْ إلَخْ (وَتُمِّمَ) الشَّهْرُ الْأَوَّلُ الَّذِي وَقَعَ فِيهِ الطَّلَاقُ ثَلَاثِينَ يَوْمًا (مِنْ الرَّابِعِ فِي الْكَسْرِ)

…like the iddah of one who has not seen menstruation, because she is young or has never seen it; and the iddah of the woman past menstruation is three months. When the divorce falls partway through a month, the first month is completed to thirty days from the fourth.

وحرة لم تحض أو يئست بثلاثة أشهر فإن طلقت في أثناء شهر فبعده هلالان وتكمل المنكسر ثلاثين فإن حاضت فيها وجبت الإقراء

A free woman who has not menstruated, or who has passed menstruation, (observes the iddah) with three months. If she was divorced partway through a month, two crescent months follow it and the broken month is completed to thirty. If she menstruates during them, the qurūʾ become obligatory.
