How could people practice their religion if they relied only on the Qur’an and ignored the Sunnah? Take prayer, the pillar of Islam—how do people know that Dhuh

So the Sunnah explains the Qur’an, clarifies it, and directs to it. Disbelief in the Sunnah is disbelief in the Qur’an, because the Sunnah is included in Allah’s statement: “Whatever the Messenger gives you, take it; and whatever he forbids you from, leave it.” And also His statement: “It is not for a believing man or woman, when Allah and His Messenger have decided a matter, to have any choice in it. Whoever disobeys Allah and His Messenger has clearly gone astray.” As for this narration, its chain includes some narrators who were criticised and others who are acceptable, but its meaning is sound and clear."
