خَرَجُوا مِنْ دِيَارِهِمْ وَهُمْ أُلُوفٌ حَذَرَ الْمَوْتِ
They left their homes while they were thousands, fearing death.
Quran example - Surah Al-Baqarah 2:243
- خَرَجُوا gives the event and its plural subject.
- وَهُمْ أُلُوفٌ is a nominal sentence describing their condition.
- The waw and هُمْ together link that sentence to the people who left.
A sentence used as haal contributes a condition, not a second unrelated statement.
