And it is narrated in the same way from Muhammad bin Bishr. He narrates from Ubaidullah, who narrates from Nafi', who narrates from Ibn Umar (may Allah be pleased with them both), and he from the Prophet (peace and blessings of Allah be upon him). Along with Ubaidullah, this hadith is also narrated by Muhammad bin Ishaq from Nafi', who narrated from Ibn Umar (may Allah be pleased with them both). And the Prophet (peace and blessings of Allah be upon him) himself traveled with his companions into the territory of the enemies, even though all those persons were scholars of the Noble Qur'an.
