It is narrated from Hazrat Jarir (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: The Muhajirun and the Ansar are guardians of one another. The freed ones are from among the Quraysh, and the emancipated ones are from among the Thaqif, and all of them will remain guardians of one another until the Day of Resurrection. The previous hadith is also narrated through this second chain of transmission.
