[Machine] My father sent a woman to Aisha asking her which prayer was most beloved to the Messenger of Allah ﷺ for him to adhere to. She said, "He used to pray four units of prayer before Dhuhr, in which he would prolong his standing and perfect his bowing and prostration. As for the prayers he did not abandon, whether he was healthy or sick, present or absent, or witnessing, he would perform two units before Fajr."
