وَهُوَ الَّذِي جَعَلَ لَكُمُ النُّجُومَ لِتَهْتَدُوا بِهَا فِي ظُلُمَاتِ الْبَرِّ وَالْبَحْرِ قَدْ فَصَّلْنَا الْآيَاتِ لِقَوْمٍ يَعْلَمُونَ ﴿۹۷﴾ وَهُوَ الَّذِي أَنْشَأَكُمْ مِنْ نَفْسٍ وَاحِدَةٍ فَمُسْتَقَرٌّ وَمُسْتَوْدَعٌ قَدْ فَصَّلْنَا الْآيَاتِ لِقَوْمٍ يَفْقَهُونَ ﴿۹۸﴾

﴾97﴿ Wa Huwal lazee ja'ala lakumun nujooma litahtadoo bihaa fee zulumaatil barri walbahr; qad fassalnal Aayaati liqawminy ya'lamoon
﴾98﴿ Wa huwal lazeee ansha akum min nafsinw waahidatin famustaqarrunw wa mustawda'; qad fassalnal Aayaati liqaw miny-yafqahoon

﴾97﴿ And only Allah Almighty is the one who created the stars for you so that you can find your way through the darkness of the desert and the sea, indeed We explained the reasons in detail for the people who know
﴾98﴿ And only Allah, the Exalted, is the one who created you from one person, so for you are a grave and a place to be buried, indeed We explained the reasons in detail for the people who know

[97] This is another rational argument, and the sun and moon are mentioned separately because their benefits differ greatly.
(لِتَهْتَدُوا) — one of their benefits is mentioned here: using them for guidance (like navigating directions).
Two other benefits are also known, as mentioned in verse 5 of Surah Al-Mulk: for the adornment of the sky and as missiles against devils.
(فَصَّلْنَا) — means that Allah has explained, clarified, and detailed things separately and clearly.
(يَعْلَمُونَ) — refers to those who possess the knowledge of how to derive reasoning and take lessons (i.e., those capable of understanding through reflection).
[98] This is another rational, inward (anfusi) proof.
(فَمُسْتَقَرٌّ) — has multiple meanings:
1. The father's loins (place of sperm origin),
2. The cycle of the day (daytime as a stable phase),
3. Life in this world (as a temporary but settled phase).
(مُسْتَوْدَعٌ) — also includes:
4. The mother’s womb (as the place where the seed is deposited),
5. The resting place of the night (as a time of withdrawal),
6. The soul’s placement in the Barzakh (the intermediate realm after death).
These words encompass all these meanings.
Since understanding this requires a degree of knowledge, the verse uses (يَفْقَهُونَ) — indicating deep comprehension.
The creation of all humans originates from one father, Adam (peace be upon him), and recognizing the details of mustaqarr (settling) and mustawda‘ (depositing) requires precise knowledge, which is referred to as fiqh (deep understanding).
