were #FreePalestine, #GazaUnderAttack,

Certainly, here are some dua (prayers) for the well-being of the Palestinian people:

1. "Allahumma Nasir Al-Mustad'afeen Fee Kulli Makan" (اللهم نصر المستضعفين في كل مكان) - "O Allah, grant victory to the oppressed wherever they may be."

2. "Rabbana Aghfir Warham Wa Anta Khairur Rahimeen" (ربنا اغفر وارحم وأنت خير الراحمين) - "Our Lord, forgive and have mercy, for You are the best of the merciful."

3. "Ya Allah, Unite the Hearts of the Ummah and Bring Peace to Palestine."

As for trending hashtags, it's important to keep up with current events and social media trends. You can search for relevant hashtags on platforms like Twitter or Instagram.
