It is narrated from Amr bin Shu'ayb, from his father, that a man came to Sayyiduna Abdullah bin Amr (may Allah be pleased with them both) and asked him about a muhrim (a person in ihram) who had intercourse with his wife. He pointed to Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) and said: "Go to him and ask him." Shu'ayb said: The man did not recognise him, so I went with him. He asked Ibn Umar (may Allah be pleased with them both), and he said: "Your Hajj is void." The man asked: "What should I do now?" He said: "Remain with the people (in ihram) and do the same rites that they are doing. Then, when the next year comes, perform Hajj and offer a sacrificial animal (hady)." The man returned to Sayyiduna Abdullah bin Amr (may Allah be pleased with them both), and I was with him, and he said: "Now go to Ibn Abbas (may Allah be pleased with them both) and ask him." Shu'ayb said: I went with him to Ibn Abbas (may Allah be pleased with them both), and he asked him, and he gave the same answer that Ibn Umar (may Allah be pleased with them both) had given. The man returned to Abdullah bin Amr (may Allah be pleased with them both), and I was with him, and he told him what Ibn Abbas (may Allah be pleased with them both) had said. Then he asked: "What do you say?" He said: "My view is the same as what the two of them said." This is a hadith whose narrators are trustworthy (thiqah) and hafiz (masters of memorisation), and it is clear proof of the soundness of Shu'ayb bin Muhammad hearing from his grandfather Abdullah bin Amr. These were the last additional hadiths that my ijtihad reached in the Book of Sales, beyond those recorded by Imam Bukhari and Imam Muslim (may Allah have mercy on them both). Within this book I have also mentioned the books whose titles Imam Bukhari set at the end of the Book of Sales, among which are: the Book of Salam (advance payment), the Book of Shuf'ah (pre-emption), the Book of Ijarah (hiring), the Book of Hawalah (transfer of debt), the Book of Harth (cultivation), the Book of Muzara'ah (sharecropping), the Book of Musaqah (irrigation partnership), the Book of Gifts ('Ata'ya), the Book of Presents (Hibat), the Book of Qirad (silent partnership), the Book of Luqatah (found property), the Book of Mazalim (injustices), the Book of Refraining from Begging, the Book of Rahn (pledges), the Book of Shirkah (partnership), the Book of Itq (manumission), the Book of the Mukatab, the Book of Testimonies, the Book of Reconciliation, the Book of Conditions, the Book of Wills and the Book of Waqf (endowment). I have explained them at the end of this book so that no one imagines that I left the Book of Sales empty of these books. And Allah alone is my helper in what I hope for, to be able to follow the traces of the two Shaykhs; He is sufficient for me, and the best disposer of affairs.
