Abdullah bin Ghabir al-Alhani (may Allah have mercy on him) said: Sayyiduna Habis bin Sa'd al-Ta'i (may Allah be pleased with him), who had lived in the time of the Prophet (peace and blessings be upon him), entered the mosque at the time of suhur (before dawn), and some people were praying in the front part of the mosque. He said: "By the Lord of the Ka'bah! These are show-offs; frighten them, for whoever frightens them has obeyed Allah and His Messenger." Then he said: "The angels pray at the time of suhur in the front part of the mosque."
