يَوْمَ نَحْشُرُ الْمُتَّقِينَ إِلَى الرَّحْمَـٰنِ وَفْدًا
"The day We will assemble the God-fearing before the Rahman (All-Merciful) as guests." - 19:85.
The word وفد applies to those who are received by rulers and princes with respect and honour. According to some sayings of the Holy Prophet ﷺ he said, "These men will ride on their mounts which they used in their worldly life." Some say that their own virtuous deeds will take the shape of their mounts.
