A small amount of gharar (also gharar qalil or gharar yaseer) that cannot be avoided due to the nature of the subject matter of the contract (aqd). This degree of gharar doesn’t cause considerable damage or losses to either of the counterparties. As such, it doesn’t affect the validity of the contract, i.e., it is typically tolerable and overlooked under shari’a. An example of gharar yasir is an ijarah contract (aqd al-ijarah) in which ujrah is quoted and paid monthly: the exact number of days in a given month varies (30 and 31 days across almost all the months of the year and at times 28 or 29 days for February).

Gharar yasir is Arabic for minor uncertainty or ambiguity in a transaction.
