عَنْ عَائِشَةَ أُمِّ الْمُؤْمِنِينَ أَنَّهَا انْتَقَلَتْ حَفْصَةَ بِنْتَ عَبْدِ الرَّحْمٰنِ بْنِ أَبِي بَكْرٍ الصِّدِّيقِ حِينَ دَخَلَتْ فِي الدَّمِ مِنَ الْحَيْضَةِ الثَّالِثَةِ، قَالَ ابْنُ شِهَابٍ فَذُكِرَ ذَلِكَ لِعَمْرَةَ بِنْتِ عَبْدِ الرَّحْمٰنِ فَقَالَتْ : صَدَقَ عُرْوَةُ وَقَدْ جَادَلَهَا فِي ذَلِكَ نَاسٌ، فَقَالُوا : إِنَّ اللّٰهَ تَبَارَكَ وَتَعَالَى يَقُولُ فِي كِتَابِهِ : ﴿ثَلَاثَةَ قُرُوءٍ﴾ [البقرة: 228] فَقَالَتْ عَائِشَةُ : صَدَقْتُمْ، تَدْرُونَ مَا الْأَقْرَاءُ؟ إِنَّمَا الْأَقْرَاءُ الْأَطْهَارُ.
Lady Aisha (may Allah be pleased with her) allowed her niece Hafsa bint Abdur Rahman to complete her waiting period (‘iddah) when her third menstrual period began. Ibn Shihab (may Allah have mercy on him) said: I narrated this from Umrah bint Abdur Rahman. Umrah said: Urwah spoke the truth, in fact, people argued with Lady Aisha (may Allah be pleased with her) regarding this matter and said that Allah Almighty says: "Divorced women shall keep themselves in waiting for three periods (quroo’)." She said: You speak the truth, but do you know what is meant by quroo’? By quroo’, purity (tuhr) is meant.
