For ayna and matā, distinguish questions from conditions through meaning and verb forms; do not classify them from the first word alone.
Book example: مَتَى تُسَافِرُ؟
When will you travel?
One indicative imperfect: question.
Book example: مَتَى تَصُمْ أَصُمْ.
Whenever you fast, I shall fast.
Jussive condition and result.
