It is narrated from Sayyiduna Abdullah bin Amr (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: "The souls of the believers meet one another at a distance of a day and a night's journey, although neither of them has seen the face of the other."
