Bu shunday lafzlardirki, ularning dalolatida (ma'noga ishora qilishida) ma'nosi yashirin yoki noaniq bo'lib, ular o'zi nazarda tutilgan narsaga to'g'ridan-to'g'ri yo'l ko'rsatmaydi, balki tashqi bir narsaga suyanadi. Bu noaniqlikka nisbatan to'rt daraja mavjud:

These are the Alfaazh which in their Dalaalah (textual implication/indication), in respect to their meaning, is hidden or obscure and so they do not guide to what is intended from them but rather rest upon an external matter. There are four levels in respect to this lack of clarity:

1 – Al-Xafiy va bu eng kam yashirin (yoki noaniq) narsadir.

1 – Al-Khafiy and this is the least hidden (or obscure).

2 – Al-Mushkil va u Al-Khafiydan kamroq ravshan.

2 – Al-Mushkil and it is less clear than the Khafiy.

3 – Al-Mujmal va bu Al-Mushkil'dan kamroq aniq.

3 – Al-Mujmal and this is less clear than the Mushkil.

4 – Al-Mutashaabih, bu esa uch turdagi oldin zikr qilingan turlar ichida eng yashirin va eng kam aniq bo‘lgandir.

4 – Al-Mutashaabih and this is very hidden and the least clear from the three previously mentioned types.
