Sunan an-Nasa'i, Volume 3, Book 24, Hadith 2767 (DarusSalam) ⓘ

Hilal bin Khabbab said: "I asked Sa'eed bin Jubair about a man who performs Hajj and stipulates a condition. He said: 'Conditions are something that people do among themselves.' I narrated the Hadith of 'Ikrimah to him, and he narrated to me from Ibn 'Abbas, that Duba'ah bint Az-Zubair bin 'Abdul-Muttalib came to the Prophet, and said: 'O Messenger of Allah, I want to perform Hajj, so what should I say?' He said: 'Say: Labbaik Allahumma! Labbaika wa mahilli min al-ardihayth tahbisuni (Here I am, O Allah, Here I am, and I shall exit Ihram at any place where You decree that I cannot proceed.)" And whatever condition you stipulate will be accepted by your Lord."

أَخْبَرَنِي إِبْرَاهِيمُ بْنُ يَعْقُوبَ، قَالَ حَدَّثَنَا أَبُو النُّعْمَانِ، قَالَ حَدَّثَنَا ثَابِتُ بْنُ يَزِيدَ الأَحْوَلُ، قَالَ حَدَّثَنَا هِلاَلُ بْنُ خَبَّابٍ، قَالَ سَأَلْتُ سَعِيدَ بْنَ جُبَيْرٍ عَنِ الرَّجُلِ، يَحُجُّ يَشْتَرِطُ قَالَ الشَّرْطُ بَيْنَ النَّاسِ فَحَدَّثْتُهُ حَدِيثَهُ - يَعْنِي عِكْرِمَةَ - فَحَدَّثَنِي عَنِ ابْنِ عَبَّاسٍ أَنَّ ضُبَاعَةَ بِنْتَ الزُّبَيْرِ بْنِ عَبْدِ الْمُطَّلِبِ أَتَتِ النَّبِيَّ صلى الله عليه وسلم فَقَالَتْ يَا رَسُولَ اللَّهِ إِنِّي أُرِيدُ الْحَجَّ فَكَيْفَ أَقُولُ قَالَ ‏ "‏ قُولِي لَبَّيْكَ اللَّهُمَّ لَبَّيْكَ وَمَحِلِّي مِنَ الأَرْضِ حَيْثُ تَحْبِسُنِي فَإِنَّ لَكِ عَلَى رَبِّكِ مَا اسْتَثْنَيْتِ ‏" ‏ ‏.‏
