وَجَدْتُ فِي كِتَابِ أَبِي حَدَّثَنَا عَامِرُ بْنُ صَالِحٍ قَالَ حَدَّثَنِي مَالِكُ بْنُ أَنَسٍ عَنِ ابْنِ شِهَابٍ عَنْ عُرْوَةَ عَنْ عَمْرَةَ عَنْ عَائِشَةَ أَنَّهَا قَالَتْ كَانَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ إِذَا اعْتَكَفَ لَمْ يَخْرُجْ مِنْ الْمَسْجِدِ إِلَّا لِحَاجَةِ الْإِنْسَانِ

In my father's book, I found that it was told to us [Amir bin Salih] he said: has told me [Malik bin Anas] from [Ibn Shihab] from [Urwah] from [Amrah] from [Aisyah] said: "When Rasulullah shallaallahu 'alaihi wa sallam performed 'tikaf, he did not leave the mosque except for human needs.
