{And among His Ayat} the signs which point to His great might and power,

means, whatever He has created in them, i.e., in the heavens and the earth.

{and whatever moving creatures} this includes the angels, men, Jinn and all the animals with their different shapes, colors, languages, natures, kinds and types. He has distributed them throughout the various regions of the heavens and earth.

{And He} means, yet despite all that,

means, on the Day of Resurrection, He will gather the first and the last of them, and bring all His creatures together in one place where they will all hear the voice of the caller and all of them will be seen clearly; then He will judge between them with justice and truth.

The Cause of Misfortune is Sin

means, 'whatever disasters happen to you, O mankind, are because of sins that you have committed in the past.'

{And He pardons much.} means, of sins; 'He does not punish you for them, rather He forgives you.'

According to a Sahih Hadith:

«By the One in Whose Hand is my soul, no believer is stricken with fatigue, exhaustion, worry or grief, but Allah will forgive him for some of his sins thereby - even a thorn which pricks him.»

Imam Ahmad recorded that Mu'awiyah bin Abi Sufyan, may Allah be pleased with him, said, "I heard the Messenger of Allah say:

«No physical harm befalls a believer, but Allah will expiate for some of his sins because of it.»"

Imam Ahmad also recorded that 'A'ishah, may Allah be pleased with her, said, "The Messenger of Allah said:

«If a person commits many sins and has nothing that will expiate for them, Allah will test him with some grief that will expiate them.»"
