Sunan Ibn Majah, Volume 2, Book 7, Hadith 1776 (DarusSalam) ⓘ

It was narrated that ‘Aishah said: “I used to enter the house to relieve myself, and there was a sick person there, and I only inquired after him as I was passing through.” She said: “And the Messenger of Allah would not enter the house except to relieve himself, then they were observing I’tikaf.”

حَدَّثَنَا مُحَمَّدُ بْنُ رُمْحٍ، أَنْبَأَنَا اللَّيْثُ بْنُ سَعْدٍ، عَنِ ابْنِ شِهَابٍ، عَنْ عُرْوَةَ بْنِ الزُّبَيْرِ، وَعَمْرَةَ بِنْتِ عَبْدِ الرَّحْمَنِ، أَنَّ عَائِشَةَ، قَالَتْ إِنْ كُنْتُ لأَدْخُلُ الْبَيْتَ لِلْحَاجَةِ وَالْمَرِيضُ فِيهِ فَمَا أَسْأَلُ عَنْهُ إِلاَّ وَأَنَا مَارَّةٌ ‏.‏ قَالَتْ وَكَانَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ لاَ يَدْخُلُ الْبَيْتَ إِلاَّ لِحَاجَةٍ إِذَا كَانُوا مُعْتَكِفِينَ ‏.‏
