Sahih Muslim 297b
'Amra daughter of 'Abd al-Rahman reported: 'A'isha, wife of the Apostle 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 ﷺ قَالَتْ إِنْ كُنْتُ لأَدْخُلُ الْبَيْتَ لِلْحَاجَةِ وَالْمَرِيضُ فِيهِ فَمَا أَسْأَلُ عَنْهُ إِلاَّ وَأَنَا مَارَّةٌ وَإِنْ كَانَ رَسُولُ اللَّهِ ﷺ لَيُدْخِلُ عَلَىَّ رَأْسَهُ وَهُوَ فِي الْمَسْجِدِ فَأُرَجِّلُهُ وَكَانَ لاَ يَدْخُلُ الْبَيْتَ إِلاَّ لِحَاجَةٍ إِذَا كَانَ مُعْتَكِفًا . وَقَالَ ابْنُ رُمْحٍ إِذَا كَانُوا مُعْتَكِفِينَ .
