Hadith 8:106
Abu Bakr narrated to us, he said: Abu Mu’awiyah narrated to us, from Ibn Jurayj, from ‘Ata’, that a man said to him: "I have a vow to perform Hajj, and I have not yet performed the Hajj of Islam (the obligatory Hajj). So which of the two should I begin with?" He said: "Begin with the Hajj of Islam."
حدثنا أبو بكر قال ثنا أبو معاوية عن بن جريج عن عطاء قال له رجل إن علي نذرا بالحج ولم يحج حجة الإسلام فأيهما ابدأ قال ابدأ بحجة الإسلام
