From among the conditions of the validity of the Takleef in respect to the action are:

1 – That the action is Ma’roof (known) to the Mukallaf as the Takleef (being charged) with the Majhool (unknown) is not valid. For that reason, we find that the Takleefaat that came in the Qur’aan are Mujmalah (undetailed), like the Salaah and the Zakaah for example, which were then explained and made clear by the Messenger of Allah (saw) in his statements (Aqwaal) and actions (Af’aal) which took away the angle of ignorance in respect to them (i.e. so that they are known). Indeed, Allah (swt) commanded His Messenger (saw) to make clear and explain the Mujmal of the Qur’aan. Allah Ta’Aalaa said:

In addition, the Shaari’ (Legislator) has requested the Mukallaf to ask the people of knowledge in respect to that which they do not know. Allah Ta’Aalaa said:

That is because the ‘Ulamaa are those who have studied that which Allah (swt) has placed upon the servants in terms of the actions of Takleef.
