Prayer is the foundation of faith, and the Prophet (blessings and peace of Allah be upon him) has explained how to pray in word and deed. The Sahabah were keen to follow his teachings in prayer, and transmitted that to those who came after them. In this hadith, Khabbab ibn al-Aratt (may Allah be pleased with him) is asked whether the Prophet (blessings and peace of Allah be upon him) recited al-Fatihah and another surah in Zuhr and ‘Asr as he did in Maghrib, ‘Isha’ and Fajr, or did he not to recite in those two prayers? Perhaps the reason for this question was that they thought that there was no recitation because the recitation is not done out loud. Khabbab (may Allah be pleased with him) answered: Yes, he used to recite in Zuhr and ‘Asr. They asked him: How did you know that he was reciting, even though the recitation is done quietly? He replied: By the movement of his beard. In other words, we could tell that he was reciting from the movement of his beard whilst he was standing in prayer. With regard to the amount that he (blessings and peace of Allah be upon him) used to recite, in Sahih al-Bukhari it is narrated from Abu Qatadah al-Ansari (may Allah be pleased with him) that the Prophet (blessings and peace of Allah be upon him) used to make the recitation longer in the first rak‘ah and shorter in the second. According to a report narrated by Muslim from Abu Sa‘id al-Khudri (may Allah be pleased with him), the Prophet (blessings and peace of Allah be upon him) used to recite in each of the first two rak‘ahs of Zuhr prayer around thirty verses, and in the last two around fifteen verses, or he said: half of that. In ‘Asr, in each of the first two rak‘ahs he would recite around fifteen verses, and in the last two [he would recite] half of that. This hadith indicates that it is permissible to lift one’s gaze and look at the imam, and for the one who is praying behind an imam to look at his imam whilst praying, and pay attention to the imam’s movements when he moves down and up again. It also indicates that recitation is to be done quietly in Zuhr and ‘Asr..
