ان الله يدخل الذين امنوا وعملوا الصالحات جنات تجري من تحتها الانهار ان الله يفعل ما يريد

إِنَّ ٱللَّهَ يُدْخِلُ ٱلَّذِينَ ءَامَنُوا۟ وَعَمِلُوا۟ ٱلصَّـٰلِحَـٰتِ جَنَّـٰتٍ تَجْرِى مِن تَحْتِهَا ٱلْأَنْهَـٰرُ ۚ إِنَّ ٱللَّهَ يَفْعَلُ مَا يُرِيدُ

Again, we see reemerging themes as Allah redescribes the reward of the believers and specifically the reward of the migrants. You may remember earlier verses describing the permission to resist the oppression for those who were forced out of their homes. In verse 58, Allah foreshadows what their destiny may be but reminds them that either way, that struggle will not be in vain (whether a muhajir dies in battle or naturally).

#SuratHaj

There a stark change in direction from previous verses speaking of those who are doomed to reminding us of the resting place of those who have iman AND inclined toward/do good deeds (an essential combination). I'm always struck by the love that Allah has for the prophet (SAW) when he defends His beloved messenger so vehmently in verses such as verse 15.
Verse 17 reminds me of a confidence believers are given which can relate back to the adab of debate alluded to in verse 8. The confidence is that, in the end, when all that was described in the very beginning verses happens, the search for truth will come to an end and Allah will give the final verdict. It is relieving because it leaves the ultimate result to Allah.
It should be noted that the only species that can lay all of its extremities on the floor, allowing for perfect sujood, are human beings. It's also noted that all the mentioned creation (sun and moon, stars, mountains, trees, and animals) have particular patterns, some that will not be disturbed UNTIL the day of judgement. The sun and moon both rise and set, trees shed their leaves and exchange carbon dioxide for oxygen, animals eat, sleep and hunt.
