سُنَّةُ الله في خَلْقِه comes as one expression, like I wrote it. The word سُنَّةُ means "the rule", "the way you do something" And the easiest explanation I can provide is the normal events that God created as rules that happen in a creature's life. e.g : Birth, growing up, getting sick, death... These things happen to any creature (human, animal, plants...) We don't talk only about the livings, we talk about the inanimated thing as well. For example, when we say that Water extinguish the fire, then this is سُنَّةُ الله في خَلْقِه I hope I explained well this expression.

It means that Allah "真主,真主" has "ways 道" (sunan) with regard to his creation (which never change). 好 的？

Please, could you verify this sentence : منهجهم هنا يعني الرأس السلف (copy the orginal text, paragraph to verify the right meaning because its wrong to say الراس السلف (two definite nouns successively)

It means that Allah "真主,真主" has "ways 道" (sunan) with regard to his creation (which never change). 好 的？
