Hadith 8:101
Abu Bakr narrated to us, he said: Abu al-Ahwas narrated to us, from Zayd ibn Jubayr, he said: I was sitting with Ibn Umar when a woman came to him and said: "I vowed to perform Hajj, and I have never performed Hajj before this Hajj." He said: "This is the Hajj of Islam (the obligatory Hajj), so seek that which you may fulfill your vow with."
حدثنا أبو بكر قال حدثنا أبو الأحوص عن زيد بن جبير قال كنت عند بن عمر قاعدا فأتته امرأة فقالت إني نذرت أن احج ولم أحج قبل هذه الحجة قط قال هذه حجة الإسلام فالتمسي ما توفين به عن نذرك
