Is there a difference between combining prayers by advancing them and combining them by delaying them?

Question : If he says, "By Allah, it is the same whether you combine by advancing or by delaying; each has its own time. No problems have arisen."

Answer : There is no hardship on him; he must combine. He must combine, but he says there is no difference between combining by advancing or delaying. For example, if I combine by advancing, then I ride and walk, it is easy. And if I ride before praying Maghrib and 'Isha', then I get off at any station and pray, each is fine for me, yes.
