It is narrated from Sayyiduna Salman al-Farisi (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "No one will enter Paradise except with a pass: In the name of Allah, the Most Gracious, the Most Merciful. This is a document from Allah for so-and-so son of so-and-so; admit him into a lofty Garden whose fruits hang low."
