(a) Sayyiduna Abu Sa'id al-Khudri (may Allah be pleased with him) narrates: In the Zuhr and Asr prayers we used to estimate from the standing of the Messenger of Allah (peace and blessings be upon him) how much he had recited in the two rak'ahs. We estimated that in the first two rak'ahs of Zuhr he stood for as long as it takes to recite Surah al-Sajdah, and in the last two rak'ahs his standing was half that of the first two. Then we estimated his standing in the first two rak'ahs of Asr, and it was equal to the recitation of the last two rak'ahs of Zuhr, and in the last two rak'ahs of Asr it was half that of the first two rak'ahs of Asr.
(b) In the hadith of Musaddad it is: equal to the recitation of thirty verses.
