It is narrated from Sayyiduna Abu Umamah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "The people of Paradise will visit one another riding she-camels with cushioned saddles. The people of the high ranks (Illiyyin) will visit those below them, but those below them will not visit the people of the high ranks, except those who loved one another for the sake of Allah; they will visit one another wherever they wish in Paradise."
