He is the One Who sends the winds ushering in His mercy. When they bear heavy clouds, We drive them to a lifeless land and then cause rain to fall, producing every type of fruit. Similarly, We will bring the dead to life, so perhaps you will be mindful.
Explanation
The two readings amount to the same, as the genus ‘wind’ contains the meaning of the plural. There is a general pattern in the Quran (among most of its canonical readers) to use the plural in contexts of mercy, i.e. the gentle winds that bring multiple benefits. The singular is more associated with contexts of punishment, as this indicates a singular force. However, this rule has a number of exceptions which may also be explained in a more nuanced way.
