The Fourth Condition: That the Jilbaab Should be Wide and not Tight SO as to Reveal the Shape of the Body. And the reason for this is that the purpose of the outdoor garment of the woman is to prevent temptation and arousal of desires, and this will not be achieved except by a wide spacious garment. So even if the beauty underneath cannot be seen because the garment has fulfilled the previous condition, it must also fulfill this important condition whereby the shape and size of the bodily parts of the woman are not described, such as her breasts and waist, due to the tightness of the jilbaab. For indeed if the jilbaab is tight, then its objective is lost! The noble Companion Usaamah bin Zaid said, Allaahs Messenger ﷺ gave me a dense Coptic cloth to wear which he was given as a gift from Dihyah Al-Kalbee. So I dressed my wife with it. So the Messenger ﷺ said, Why have you not worn that Coptic garment? I replied, I clothed my wife with it. So he said, Command her to wear a garment underneath it, for I fear it will reveal the size of her bones (i.e. her bodily parts). (Reported by Ahmad and Al-Bayhaqee).
