وقال صلى الله عليه وآله: إياكم والقعود بالصعدات إلا من أدى حقها. الصعدات الطرق وهو مأخوذ من الصعيد والصعيد التراب وجمع الصعيد الصعد ثم الصعدات جمع الجمع كما يقال: طريق وطرق ثم طرقات. قال الله عز وجل: " فتيمموا صعيد طيبا " فالتيمم التعمد للشئ، يقال منه: أمت فلانا [فأنا] أؤمه أما وتأممته وتيممته، كله تعمدته وقصدت له. وقد روي عن الصادق عليه السلام أنه قال: الصعيد الموضع المرتفع، و الطيب [الموضع] الذي ينحدر عنه الماء.
He, Allah’s blessings be upon him and his Family, also said: «Beware from sitting on the ssa’dat, except for the one whose right has been fulfilled.» Ssa’dat are roads, and it stems from ssa’eed, and ssa’eed is sand. The plural of ssa’eed is ssa’d, then furthermore, ssa’dat is the plural of the pluralized, like how it is said: Tareeq [1], turuq and then turuqat. Allah, Exalted and Glorious is He, said: «Then perform Tayammum with good sand.» (4:43) Tayammum is to intentionally turn to something. From this it is said: «He performed amm to such-a-person» and «then I performed amm to him, (in an act of) an amm» and «I performed ta’ammum to him» and «I performed tayammum to him». All of it means: I intended for him and I sought to him. It has been narrated of al-Sadiq, peace be uon him, that he said: «The ssa’eed is the high spot, and tayib is the spot from which waters pours down.»
