Sayyiduna Anas (may Allah be pleased with him) narrates: The Prophet (peace and blessings be upon him) said: I entered Paradise and I heard a sound. I asked: Who is this? The angels replied: This is Rumaysa bint Milhan. (Imam Ibn Hibban, may Allah have mercy on him, says:) Up to here was the mention of the Ansar. Now we will mention (those Companions) who belonged to the Arab tribes after them, who are not counted among the Muhajirun from the Quraysh or the Ansar, if Allah Almighty makes this matter easy and facilitates it.
