It is narrated from Sayyiduna Sa'd (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "If something less than a fingernail of Paradise were to appear in this world, all four directions of the earth and sky would be adorned. And if a man from Paradise were to look into this world and his bracelet became visible, its light would outshine the light of the sun just as the sun's light outshines the light of the stars."
