Surah 30 is about the consequences of wrong acts resulting in failure in this life. Those who fail to do the right things, past nations exampled, are lost.
Examples, signs, are given for us to see,ponder over.
We get EVERYTHING glorifying Allah, day and night, and signs are there for us to see that life can come from dead by following the proper commands, this means societies can be reformed to flourish, not just rebirth resurrection
Are we not to understand the Quran as a Book to Guide us in this life? Surah 30 is one of many that say that if we do wrong we will face the consequences in this life, and in the hereafter.
30:56 The people who are endowed with knowledge and insight and believe in the truthfulness of Our Laws, will tell them that Allah's Law of Mukafat gives you respite till the last moment before the results appear. It also gives respite till the decision to remove you from the thoroughfare of life because you were obstructing the way for others, has not been taken. Now the hour has come. All this was happening right in front of you, but you were so grossly intoxicated with power and authority that you completely missed noticing how you were gradually getting nearer to your fatal end.
