Maulana Ataullah Sajid
Benefits and Issues:
By saying "in sha Allah," an oath is nullified; then, if the action mentioned is not carried out, there is no sin of breaking the oath, nor is expiation (kaffarah) required.
The reason for this is that an oath is meant to express a firm resolve, while "in sha Allah" means "if Allah wills, I will do this."
And in matters pertaining to the future, a person does not know Allah’s will, so in this, it is as if the resolve is negated, and the possibility arises that perhaps I will be able to do this action, or perhaps I will not.
