Hazrat Ali (may Allah be pleased with him), regarding the verse of the Holy Qur'an { یَوْمَ نَحْشُرُ الْمُتَّقِیْنَ اِلَی الرَّحْمٰنِ وَفْدًا }, says: Do you know upon what they will be gathered? By Allah, they will not be gathered walking on their feet, rather, they will come upon such camels as people have never seen before. Upon them will be saddles of gold, their bridles will be of ruby. The righteous will be seated upon them, then those animals will carry them until they knock at the doors of Paradise.
