Ask people who are sick to pray for you.

This hadith teaches us about the power of prayer and supplication. It was narrated by 'Umar bin Al-Khattab that the Prophet said when one visits a person who is sick, they should ask them to pray for them as their prayers are like those of angels. This means that even though we may not be able to physically help someone in need, we can still offer our prayers and invoke intercession on their behalf. When we do this, it has a powerful effect on our lives and can bring us closer to God. We should also remember that even though we may not be able to physically help someone in need, our prayers can still have an impact on their lives and bring comfort during difficult times.
