Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) narrates this statement of the Noble Prophet (peace and blessings be upon him): "The whiteness of the shin of a woman from among the people of Paradise will be visible from beneath seventy silk garments. The reason for this is that Allah Almighty has said: 'They are like rubies and coral.' Ruby is such a stone that if you put a thread through it and then look at it, you will be able to see it through the stone."
