Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) said: A man said to the Prophet (peace and blessings be upon him): My camel is among the spoils; the polytheists had seized it. He (peace and blessings be upon him) said: "If you find your camel before the division, take it; and if it has been divided, then you are more entitled to it for its price, if you want it."
This hadith is known through al-Hasan bin Umarah from Abd al-Malik bin Maysarah, and al-Hasan bin Umarah is matruk (abandoned) and is not used as proof. Maslamah bin Ali al-Khushani also narrated it from Abd al-Malik, and he too is da'if (weak). It was also narrated with another, unknown chain from Abd al-Malik, and none of that is authentic. It was also narrated from Ishaq bin Abdullah bin Abi Farwah and Yasin bin Mu'adh al-Zayyat, from Ibn Shihab, from Salim bin Abdullah, from his father, as a marfu' report, with a difference between the two in its wording; and Ishaq and Yasin are both matruk (abandoned) and are not used as proof.
