Aishah said, "I had always wished to enter the House and pray inside it. So the Messenger of Allah ﷺ took me by the hand and led me into the Hijr, saying to me, 'Pray in the Hijr whenever you wish to enter the House, for it is simply a portion of the House. Your people fell short when they rebuilt the Kaabah and left this part outside it.'"
كنت أحب أن أدخل البيت فأصلي فيه، فأخذ رسول الله ﷺ بيدي فأدخلني في الحجر وقال لي: صلي في الحجر إذا أردت دخول البيت، فإنما هو قطعة من البيت ولكن قومك استقصروا حين بنوا الكعبة، فأخرجوه من البيت.
Abu Dawud (2028), Nasai (2912), and Tirmidhi (876) all narrated it, all from the hadith of Abdul-Aziz bin Muhammad, from Alqama bin Abu Alqama, from his mother, from Ayesha, and so he mentioned it. Ahmad (24616) also narrated it through this same route. Tirmidhi said, "Hasan sahih." This chain includes the mother of Alqama, whose name was Marjana. Ibn Hibban mentioned her in Thiqat, but no one else confirmed her reliability. That is why the Hafiz said, "Acceptable," meaning if corroborated.I say, she has indeed been corroborated in another chain, although it contains a break, and that is what Imam Ahmad (24384) narrated from Hasan, who said, "Hammad bin Salama narrated to us, from Ata bin Saaib, from Saeed bin Jubayr, from Ayesha," that she said, "O Messenger of Allah, all your family has entered the House except me?" He said, "Send to Shayba so he may open the door for you." So she sent to him. Shayba said, "We have never been able to open it at night, neither in the pre-Islamic era nor in Islam." So the Prophet ﷺ said, "Pray in the Hijr, for your people fell short in building the House when they built it."This chain includes Ata bin Saaib, whose memory became confused later in life, but Hammad bin Salama narrated from him before that confusion set in. Also, Saeed bin Jubayr did not hear directly from Ayesha.However, Tabarani narrated it in Mujam al-Awsat (7094), from Muhammad bin Abdullah bin Bakr Sarraj, who said, "Ismail bin Ibrahim Tirjumani narrated to us," who said, "Shuayb bin Safwan narrated to us, from Ata bin Saaib, from Saeed bin Jubayr, from Ibn Abbas, from Ayesha," who said, "I said, 'O Messenger of Allah, all your wives have entered the House except me?!' He said, 'Go to your relative Shayba, so he may open the door for you and you may enter it.'" So she sent word to him that the Prophet of Allah had permitted her to have the door opened so she could enter. He said, "Did the Prophet of Allah command you to do this?" She said, "Yes." So he took the keys and went to the Prophet ﷺ and said, "O Messenger of Allah, did you command that the door be opened for Ayesha?" He said, "Yes." He said, "No, by Allah, I have never opened it at night, neither in the pre-Islamic era nor in Islam, ever." He said, "Consider what you used to do, and do that, and I will not do it" (thus in the original, and it seems his statement "and I will not do it" is a slip of the pen). He said, "And you, Ayesha, go and pray two rak'ahs in the Hijr, for part of it belongs to the House, and your people were short of funds, so they left out part of the House."Here Shuayb bin Safwan inserted "Ibn Abbas" into the chain, between Saeed bin Jubayr and Ayesha. Shuayb bin Safwan is Thaqafi, Abu Yahya the scribe, one of the narrators relied upon by Muslim, though there is disagreement about him. Imam Ahmad said, "There is no harm in him, and his hadith is sahih." Ibn Main criticized him, and Ibn Adi said, "Most of what he narrates is not corroborated by anyone else." Moreover, it is not known whether he narrated from Ata bin Saaib before or after his confusion set in, except that this is a strong corroboration for the hadith of Marjana.The Hijr is the curved wall on the northern side of the Kaaba. There is disagreement over whether the entire Hijr is part of the House. The more correct view is that part of it is part of the House, measuring six or seven cubits, and whatever exceeds that is not part of the House.Ayesha's own practice afterward also strengthens this, for in Musannaf Abdul-Razzaq (9155), from Mamar, from Hisham bin Urwa, from his father, from Ayesha, she said, "I do not care whether I pray in the Hijr or inside the House." Its chain of transmission is sahih.Abdul-Razzaq also narrated (9154), from Ibn Jurayj, who said, "Kathir bin Abu Kathir narrated to me, from Umm Kulthum bint Amr bin Abu Aqrab, from Ayesha," that she asked him to open the Kaaba for her at night, but Shayba bin Uthman, so they claim, refused her. So Ayesha said to Umm Kulthum, "Come, let us enter the Kaaba," and she entered the Hijr.
