The author mentions the following in the key:
“The verb (مَاتَ) comes in two groups:
a) i-a group - نام بنام like مات يمات
[فعِل - يفعَل]
With a mutaharrik pronoun the first radical has a kasrah in the mâdi
مِتُّ ، مِتْنَا
In the Qur'ân مِتُّ occurs nine times.
b) a-u group - قال يقول like مات يموت
[فعَل - يفعُل]
With a mutaharrik pronoun the first radical has a dhammah in the mâdi
مُتُّ ، مُتْنَا
In the Qur'an مُتُّ occurs twice.
But in the mudari' only يمُوت occurs in the Qur'ân.” [end quote]

I recommend everyone to read the key for each lesson.
