Sahih Muslim 297 b
'Amra daughter of 'Abd al-Rahman reported:
'A'isha, wife of the Messenger of Allah (ﷺ) observed: When I was (in I'tikaf), I entered the house for the call of nature, and while passing I inquired after the health of the sick (in the. family), and when the Messenger of Allah (ﷺ) was (in I'tikaf), he put out his head towards me, while he himself was in the mosque, and I combed his hair; and he did not enter the house except for the call of nature so long as he was In I'tikaf; and Ibn Rumh stated: As long as they (the Prophet and his wives) were among the observers of I'tikaf.
وَحَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، حَدَّثَنَا لَيْثٌ، ح وَحَدَّثَنَا مُحَمَّدُ بْنُ رُمْحٍ، قَالَ أَخْبَرَنَا اللَّيْثُ، عَنِ ابْنِ شِهَابٍ، عَنْ عُرْوَةَ، وَعَمْرَةَ بِنْتِ عَبْدِ الرَّحْمَنِ، أَنَّ عَائِشَةَ، زَوْجَ النَّبِيِّ صلى الله عليه وسلم قَالَتْ إِنْ كُنْتُ لأَدْخُلُ الْبَيْتَ لِلْحَاجَةِ وَالْمَرِيضُ فِيهِ فَمَا أَسْأَلُ عَنْهُ إِلاَّ وَأَنَا مَارَّةٌ وَإِنْ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم لَيُدْخِلُ عَلَىَّ رَأْسَهُ وَهُوَ فِي الْمَسْجِدِ فَأُرَجِّلُهُ وَكَانَ لاَ يَدْخُلُ الْبَيْتَ إِلاَّ لِحَاجَةٍ إِذَا كَانَ مُعْتَكِفًا ‏.‏ وَقَالَ ابْنُ رُمْحٍ إِذَا كَانُوا مُعْتَكِفِينَ ‏.‏
