Arabic (Original)
حَدَّثَنَا يَحْيَى بْنُ سَعِيدٍ عَنْ مُحَمَّدِ بْنِ عَمْرٍو أَخْبَرَنِي يَحْيَى بْنُ عَبْدِ الرَّحْمَنِ عَنِ ابْنِ عُمَرَ عَنْ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ الشَّهْرُ تِسْعٌ وَعِشْرُونَ فَذَكَرُوا ذَلِكَ لِعَائِشَةَ فَقَالَتْ يَرْحَمُ اللَّهُ أَبَا عَبْدِ الرَّحْمَنِ وَهَلْ هَجَرَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ نِسَاءَهُ شَهْرًا فَنَزَلَ لِتِسْعٍ وَعِشْرِينَ فَقِيلَ لَهُ فَقَالَ إِنَّ الشَّهْرَ قَدْ يَكُونُ تِسْعًا وَعِشْرِينَ.
English Translation
Yahya ibn Sa'id narrated to us, from Muhammad ibn 'Amr - Yahya ibn 'Abd al-Rahman informed me - from Ibn 'Umar, from the Prophet, peace and blessings be upon him, who said: 'The month is twenty-nine days.' This was mentioned to 'A'ishah, and she said: May Allah have mercy on Abu 'Abd al-Rahman. Did the Messenger of Allah, peace and blessings be upon him, ever withdraw from his wives for a month? He ended his withdrawal after twenty-nine days. It was said to him about this, so he said: The month may indeed be twenty-nine days.
