Ḥarec is interpreted in three ways:
1. Ḥarec is used in the sense of doubt (shakk/shubha); as in the following verses:
No, by your Lord, they will not [truly] believe until they make you, [O Muhammad], judge concerning that over which they dispute among themselves and then find within themselves no ḥarec (that is, shakk/shubha [doubt]) concerning what you have judged and submit in [full, willing] submission. (al-Nisāʾ 4:65)
So do not let there be in your breast any ḥarec (that is, do not have any shakk/shubha [doubt] regarding the Qur'an being from Allah). (al-Aʿrāf 7:2)
But whoever He intends to misguide—He makes his breast dīq-ḥarec (that is, He places shakk/shubha [doubt] in his breast). (al-Anʿām 6:125)
2. Ḥarec is used in the sense of dīq (narrowness/distress/difficulty); as in the following verses:
Allah does not intend to place upon you in the religion any ḥarec (that is, any distress regarding your religion). (al-Māʾida 5:6)
He has not placed upon you in the religion any ḥarec (that is, any narrowness). (al-Ḥajj 22:78)
3. Ḥarec is used in the sense of sin; as in the following verses:
There is no ḥarec (that is, no sin) upon the weak, the ill, or those who find nothing to spend [for not joining the expedition]. (al-Tawba 9:91)
A similar example is found in Sūrat al-Fatḥ.
There is no ḥarec upon the blind, nor upon the lame, nor upon the sick (that is, there is no sin in eating with them). (al-Nūr 24:61)
