It is narrated from Sayyiduna Abu Sa'id (may Allah be pleased with him) that he said: "We used to estimate the length of the standing of the Messenger of Allah (peace and blessings be upon him) in the Zuhr and Asr prayers. We estimated his standing in the first two rak'ahs of Zuhr to be the equivalent of thirty verses, each rak'ah being as long as the recitation of Surah Tanzil al-Sajdah. We estimated his standing in the first two rak'ahs of Asr to be equal to the last two rak'ahs of Zuhr, and we estimated his standing, that is, in the last two rak'ahs of Asr, to be half of that."
