Sayyiduna Furat bin Hibban al-Ijli (may Allah be pleased with him) narrates that he asked the Prophet (peace and blessings be upon him) about the alliance of the Days of Ignorance, and the Prophet (peace and blessings be upon him) said: "Perhaps you wish to ask me about the alliance of Lakhm and Tamim?" He replied: "Yes, O Messenger of Allah!" Then the Prophet (peace and blessings be upon him) said: "Islam will only increase its strength." Its narrators have been declared trustworthy, though there is weakness in some of them.
