Muwatta Malik, Book 19, Hadith 697 (In-Book) ⓘ

Yahya related to me that Ziyad ibn Abd ar-Rahman said, "Malik related to us from Sumayy, the mawla of Abu Bakr ibn Abd ar-Rahman, that Abu Bakr ibn Abd ar-Rahman was once doing itikaf and he would go out to relieve himself in a closed room under a roofed passage in Khalid ibn Walid's house. Otherwise he did not leave his place of itikaf until he went to pray at the Id with the muslims."

حَدَّثَنِي يَحْيَى، عَنْ زِيَادِ بْنِ عَبْدِ الرَّحْمَنِ، قَالَ حَدَّثَنَا مَالِكٌ، عَنْ سُمَىٍّ، مَوْلَى أَبِي بَكْرِ بْنِ عَبْدِ الرَّحْمَنِ أَنَّ أَبَا بَكْرِ بْنَ عَبْدِ الرَّحْمَنِ، اعْتَكَفَ فَكَانَ يَذْهَبُ لِحَاجَتِهِ تَحْتَ سَقِيفَةٍ فِي حُجْرَةٍ مُغْلَقَةٍ فِي دَارِ خَالِدِ بْنِ الْوَلِيدِ ثُمَّ لاَ يَرْجِعُ حَتَّى يَشْهَدَ الْعِيدَ مَعَ الْمُسْلِمِينَ ‏.

Yahya related to me from Ziyad from Malik that he saw some of the people of knowledge who, when they did itikaf in the last ten days of Ramadan, would not go back to their families until they had attended the Id al-Fitr with everybody. Ziyad said that Malik said, "I heard this from the people of excellence who have passed away, and it is what I like most out of what I have heard about the matter."

حَدَّثَنِي يَحْيَى عَنْ زِيَادٍ عَنْ مَالِكٍ أَنَّهُ رَأَى بَعْضَ أَهْلِ الْعِلْمِ إِذَا اعْتَكَفُوا الْعَشْرَ الأَوَاخِرَ مِنْ رَمَضَانَ لاَ يَرْجِعُونَ إِلَى أَهَالِيهِمْ حَتَّى يَشْهَدُوا الْفِطْرَ مَعَ النَّاسِ ‏.‏ قَالَ زِيَادٌ قَالَ مَالِكٌ وَبَلَغَنِي ذَلِكَ عَنْ أَهْلِ الْفَضْلِ الَّذِينَ مَضَوْا وَهَذَا أَحَبُّ مَا سَمِعْتُ إِلَىَّ فِي ذَلِكَ ‏.
