If it rains, we will stay in
The rule
For something that may really happen, English uses if + the PRESENT, then will in the other half: If it rains, we will stay at home. The if-half never takes will, however future it feels. when works the same way and means you are sure it will happen: When I get home, I will call you.
If + present, … will + plain verb · never: If it will rain
Examples
If it rains, we will stay at home.
I will call you when I get home.
If you are late, they will not wait.
We will go if the weather stays dry.
