Musnad Ahmad 770:67

'Abd al-Razzaq narrated to us, Sufyan informed us, from al-A'mash, from Musa ibn 'Abd Allah, from 'Abd al-Rahman ibn Hilal al-'Absi, from Jarir ibn 'Abd Allah, from the Prophet, peace and blessings of Allah be upon him, who said: "The *Tulaqa* (those freed upon the conquest of Mecca) from Quraysh, and the *'Utaqa* (those freed) from Thaqif, are allies of one another in this world and the Hereafter. And the *Muhajirun* (emigrants) and the *Ansar* (helpers) are allies of one another in this world and the Hereafter."
