Abu al-Darda' (may Allah be pleased with him) performed tawaf after Asr at the time of sunset and prayed two rak'ahs before the sun set. It was said to Abu al-Darda' (may Allah be pleased with him): You are a Companion of the Messenger of Allah (peace and blessings be upon him), and you yourself say: "There is no prayer after Asr until the sun sets." Abu al-Darda' (may Allah be pleased with him) replied: This city is not like other cities.
