Book 20, Hadith 106

Arabic hadith text
وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ هِشَامِ بْنِ عُرْوَةَ، عَنْ أَبِيهِ، أَنَّ عَائِشَةَ أُمَّ الْمُؤْمِنِينَ، قَالَتْ مَا أُبَالِي أَصَلَّيْتُ فِي الْحِجْرِ أَمْ فِي الْبَيْتِ ‏.‏
Translation

Yahya related to me from Malik from Hisham ibn Urwa from hisfather that A'isha, umm al-muminin, said, "I do not mind whether Ipray in the Hijr or in the House." (i.e. praying in the Hijr is thesame as praying in the House).
