He would read from sixty to one hundred verses during the morning prayer. Sometimes he would read surah Qal; ar-Rum, at-‘Takwir, or az-Zilzal in the last two rak’ah. While travelling, he would sometimes read the last two surahs of the Qur’an. Sometimes he would read the first portion of al-Mu’minun until he would reach the story of Moses and Aaron in the first rak’ah, and then he would cough and bow. On Fridays he would read Alif; Lam, Mim, Tanzil as-Sajdah, or ad-Dahr in their complete forms. He did not do what many people do today, which is reciting part of this surah and part of another. Many ignorant people think that it is best to recite something with a prostration on Friday morning. But this is just plain ignorance. Some scholars dislike that one should read a surah with a prostration due to this ignorant thought. The Prophet, upon whom be peace, used to recite these two surahs because they contained reminders of man’s creation, the return unto Allah, the creation of Adam, the entry into Paradise and Hell-fire, and other matters that did or will specifically occur on a Friday. Therefore, he would recite them on Friday to remind his companions of the events of that day. He would recite Qaf, al-Qamr, al-A’la and al-Ghashiyyah on days of great importance like Friday, the ‘Id days, and so on.
