It is narrated from Sayyiduna Abu Malik al-Ash'ari (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Allah has servants for whom pulpits of light will be set up on the Day of Resurrection. They are neither prophets nor martyrs, yet the prophets and martyrs will envy them." The Companions asked: Who are they? He (peace and blessings be upon him) said: "Those who love one another for the sake of Allah, the Mighty and Majestic."
