If he moved off before the sun had declined, he would delay the noon prayer till he would combine it with the afternoon prayer and would offer them together. If he moved off after the sun had declined, he would combine the noon and afternoon prayers, and then he proceeded; if he moved off before the evening prayer, he would delay the evening prayer; he would offer it along with the night prayer, he would delay the evening prayer; he would offer it along with the night prayer.
