Sahih al-Bukhari 2033Book 33, Hadith 8
حَدَّثَنَا أَبُو النُّعْمَانِ، حَدَّثَنَا حَمَّادُ بْنُ زَيْدٍ، حَدَّثَنَا يَحْيَى، عَنْ عَمْرَةَ، عَنْ عَائِشَةَ ـ رضى الله عنها ـ قَالَتْ كَانَ النَّبِيُّ صلى الله عليه وسلم يَعْتَكِفُ فِي الْعَشْرِ الأَوَاخِرِ مِنْ رَمَضَانَ، فَكُنْتُ أَضْرِبُ لَهُ خِبَاءً فَيُصَلِّي الصُّبْحَ ثُمَّ يَدْخُلُهُ، فَاسْتَأْذَنَتْ حَفْصَةُ عَائِشَةَ أَنْ تَضْرِبَ خِبَاءً فَأَذِنَتْ لَهَا، فَضَرَبَتْ خِبَاءً، فَلَمَّا رَأَتْهُ زَيْنَبُ ابْنَةُ جَحْشٍ ضَرَبَتْ خِبَاءً آخَرَ، فَلَمَّا أَصْبَحَ النَّبِيُّ صلى الله عليه وسلم رَأَى الأَخْبِيَةَ فَقَالَ " مَا هَذَا ". فَأُخْبِرَ فَقَالَ النَّبِيُّ صلى الله عليه وسلم " آلْبِرُّ تُرَوْنَ بِهِنَّ ". فَتَرَكَ الاِعْتِكَافَ ذَلِكَ الشَّهْرَ، ثُمَّ اعْتَكَفَ عَشْرًا مِنْ شَوَّالٍ.
Aisha said, "the Prophet (ﷺ) used to practice I`tikaf in the last ten days of Ramadan and I used to pitch a tent for him, and after offering the morning prayer, he used to enter the tent." Hafsa asked the permission of `Aisha to pitch a tent for her and she allowed her and she pitched her tent. When Zainab bint Jahsh saw it, she pitched another tent. In the morning the Prophet (ﷺ) noticed the tents. He said, 'What is this?" He was told of the whole situation. Then the Prophet (ﷺ) said, "Do you think that they intended to do righteousness by doing this?" He therefore abandoned the I`tikaf in that month and practiced I`tikaf for ten days in the month of Shawwal."
