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."
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
