Allah's Perfect Planning

إِذْ تَمْشِىٓ أُخْتُكَ فَتَقُولُ هَلْ أَدُلُّكُمْ عَلَىٰ مَن يَكْفُلُهُۥ ۖ فَرَجَعْنَـٰكَ إِلَىٰٓ أُمِّكَ كَىْ تَقَرَّ عَيْنُهَا وَلَا تَحْزَنَ ۚ وَقَتَلْتَ نَفْسًا فَنَجَّيْنَـٰكَ مِنَ ٱلْغَمِّ وَفَتَنَّـٰكَ فُتُونًا ۚ فَلَبِثْتَ سِنِينَ فِىٓ أَهْلِ مَدْيَنَ ثُمَّ جِئْتَ عَلَىٰ قَدَرٍ يَـٰمُوسَىٰ

[And We favored you] when your sister went and said, 'Shall I direct you to someone who will be responsible for him?' So We restored you to your mother that she might be content and not grieve. And you killed someone, but We saved you from retaliation and tried you with a [severe] trial. And you remained [some] years among the people of Madyan. Then you came [here] at the decreed time, O Moses.

وَأَزْلَفْنَا ثَمَّ ٱلْـَٔاخَرِينَ

And We advanced thereto the others [i.e., the pursuers].

وَنُمَكِّنَ لَهُمْ فِى ٱلْأَرْضِ وَنُرِىَ فِرْعَوْنَ وَهَـٰمَـٰنَ وَجُنُودَهُمَا مِنْهُم مَّا كَانُوا۟ يَحْذَرُونَ

And establish them in the land and show Pharaoh and [his minister] Hāmān and their soldiers through them that which they had feared.

وَقَالَتْ لِأُخْتِهِۦ قُصِّيهِ ۖ فَبَصُرَتْ بِهِۦ عَن جُنُبٍ وَهُمْ لَا يَشْعُرُونَ

And she said to his sister, "Follow him"; so she watched him from a distance while they perceived not.

إِلَىٰ قَدَرٍ مَّعْلُومٍ

For a known extent.
