ونهى صلى الله عليه وآله عن لبستين: اشتمال الصماء، وأن يحتبي الرجل بثوب ليس بين فرجه وبين السماء شئ. قال الأصمعي: اشتمال الصماء عند العرب أن يشتمل الرجل بثوبه فيجلل ه جسده كله ولا يرفع منه جانبا فيخرج منه يده، وأما الفقهاء فإنهم يقولون: هو أن يشتمل الرجل بثوب واحد ليس عليه غيره، ثم يرفعه من أحد جانبيه فيضعه على منكبه يبدو منه فرجه. وقال الصادق صلوات الله عليه: التحاف الصماء هو أن يدخل الرجل رداءه تحت إبطه ثم يجعل طرفيه على منكب واحد وهذا هو التأويل الصحيح دون ما خالفه.
He, Allah’s blessings be upon him and his Family, also forbade two types of wearing clothes: ishtimal-us-ssammaa’; and that a man wraps himself with a robe and that there is nothing between his genital and the sky. Al-Asma’I said: Isthimal-us-ssammaa’, among the Arabs, is that a man wraps himself with a robe by which all of his body is covered and he does not raise any side of it, and so he takes his hand out of it. As for the jurists, they say: It is that a man wraps himself with one robe, and that nothing else is on him, and that he raises it from one of his sides and places it on his shoulder by which his genital appears. Al-Sadiq, Allah’s blessings be upon him and his Family, said: «Iltihaf-us-ssammaa’ is that a man makes his garment go under his underarm and then make its sides on one shoulder. This is the correct interpretation, and not the one that opposed it.»
