One of the criteria that we should refer to when deciding what is most deserving of attention and most deserving of prioritizing over other things: Giving something exactly the importance that the Quran gives to it.

Thus we should give priority to those things that it repeats in its chapters and verses, those that it stresses in its commandments and promises. We should give these things our full attention and base our lives upon them.

Of these things are, for example, faith in Allah, His revelations, the Afterlife and what it contains of reward and punishment.

As for the things that the Quran doesn’t consider important, we should give them the same amount of importance and we should not exaggerate them, for example the night journey of the Prophet ﷺ, to which the Quran dedicates only one verse, as opposed to the campaigns and battles to which the Quran dedicates entire chapters.

And when it comes to the mawlid [birth] of the Prophet, the Quran does not give it any attention whatsoever, showing us that it is not a matter of importance in the Islamic life, for, unlike the birth of the Christ, there are no miracles related to it, and there are no deeds or acts of worship that are based upon it.

Thus the Quran is a criterion that never errs, for it is the pillar of the nation, the foundation of the religion, and the spring from which Islam flows. The hadith [Prophetic traditions and sayings] are only there to explain and elucidate it.
