It is narrated from Hayyan al-Bariqi that it was said to Sayyiduna Abdullah bin Umar (may Allah be pleased with them both), or a man said to him: "I pray behind so-and-so, and he makes the prayer excessively long." Sayyiduna Ibn Umar (may Allah be pleased with them both) replied: "Indeed, two rak'ahs of the prayer of the Messenger of Allah (peace and blessings be upon him) were lighter and shorter than a single rak'ah of that so-and-so," or (the narrator is unsure whether he said): "they (the two rak'ahs) were like the whole prayer of so-and-so," or "they were like a single rak'ah of so-and-so."
Imam Abu Dawud recorded this hadith, and this narration is sahih (authentic) in its chain.
