People express grief differently. Some need to talk; others need quiet and space. The purpose of عَزَّى is to offer support, not to prove how eloquently one can speak. Compassion involves sensitivity to what the bereaved person actually needs.
Example 1: Arrange a meal or handle an urgent practical task without intruding.
Example 2: Spend time with the family and give them room to express grief without being corrected or judged.
It is also unhelpful to speculate about who is to blame for a death. Respect, privacy, and practical kindness are more valuable than dramatic words.
