This is a response from Allah to His Messenger, Musa, for what he requested from His Lord. It also contains a reminder of Allah's previous favors upon him. The first was inspiring his mother when she was breastfeeding him and she feared that Fir`awn and his chiefs would kill him. Musa was born during a year in which they (Fir`awn's people) were killing all of the male children. So she placed him in a case and cast him into the river. The river carried him away and she became grieved and distressed, as Allah mentioned about her when He said,

﴿وَأَصْبَحَ فُؤَادُ أُمِّ مُوسَى فَارِغاً إِن كَادَتْ لَتُبْدِى بِهِ لَوْلا أَن رَّبَطْنَا عَلَى قَلْبِهَا﴾

(And the heart of the mother of Musa became empty. She was very near to disclose his (case) had We not strengthened her heart.) ﴿28:10﴾ So the river carried him to the home of Fir`awn.

﴿فَالْتَقَطَهُ ءَالُ فِرْعَوْنَ لِيَكُونَ لَهُمْ عَدُوّاً وَحَزَناً﴾

(Then the people of Fir`awn picked him up, that he might become for them an enemy and a (cause of ) grief.) ﴿28:8﴾ Means that this was a destined matter, decreed by Allah. They were killing the male children of the Israelites for fear of Musa's arrival. Therefore, with Allah having the great authority and the most perfect power, He determined that Musa would not be raised except upon Fir`awn's own bed. He would be sustained by Fir`awn's food and drink, while receiving the love of Fir`awn and his wife. This is why Allah said,

﴿يَأْخُذْهُ عَدُوٌّ لِّى وَعَدُوٌّ لَّهُ وَأَلْقَيْتُ عَلَيْكَ مَحَبَّةً مِّنِّى﴾

(and there, an enemy of Mine and an enemy of his shall take him. And I endued you with love from Me,) This means that I made your enemy love you. Salamah bin Kuhayl said,

﴿وَأَلْقَيْتُ عَلَيْكَ مَحَبَّةً مِّنِّى﴾

(And I endued you with love from Me,) "This means, `I made My creatures love you.' ''

﴿وَلِتُصْنَعَ عَلَى عَيْنِى﴾

(in order that you may be brought up under My Eye.) Abu `Imran Al-Jawni said, "This means, `You will be raised under Allah's Eye.' '' Concerning Allah's statement,

﴿إِذْ تَمْشِى أُخْتُكَ فَتَقُولُ هَلْ أَدُلُّكُمْ عَلَى مَن يَكْفُلُهُ فَرَجَعْنَـكَ إِلَى أُمِّكَ كَى تَقَرَّ عَيْنُها﴾

(When your sister went and said: `Shall I show you one who will nurse him' So We restored you to your mother, that she might cool her eyes) When he was accepted into the house of Fir`awn, women were brought in attempts to find someone who might be able to nurse him. But he refused to breast feed from any of them. Allah, the Exalted, says,

﴿وَحَرَّمْنَا عَلَيْهِ الْمَرَاضِعَ مِن قَبْلُ﴾

(And We had already forbidden (other) foster suckling mothers for him) ﴿28:12﴾ Then, his sister came and said,

﴿هَلْ أَدُلُّكُمْ عَلَى أَهْلِ بَيْتٍ يَكْفُلُونَهُ لَكُمْ وَهُمْ لَهُ نَـصِحُونَ﴾

(Shall I direct you to a household who will rear him for you, and look after him in a good manner) ﴿28:12﴾ She meant, "Shall I guide you to someone who can nurse him for you for a fee'' So she took him and they went with her to his real mother. When her breast was presented to him, he took it and they (Fir`awn's family) were extremely happy for this. Thus, they hired her to nurse him and she achieved great happiness and comfort because of him, in this life and even more so in the Hereafter. Allah, the Exalted, says here,

﴿فَرَجَعْنَـكَ إِلَى أُمِّكَ كَى تَقَرَّ عَيْنُها وَلاَ تَحْزَنَ﴾

(So We restored you to your mother, that she might cool her eyes and she should not grieve.) This means that she should not grieve over you.

﴿وَقَتَلْتَ نَفْساً﴾

(Then you killed man,) This means that he killed a Coptic person (the people of Egypt, Fir`awn's people).

﴿فَنَجَّيْنَـكَ مِنَ الْغَمِّ﴾

(but We saved you from great distress) This is what he was feeling due to Fir`awn's family intending to kill him. So he fled from them until he came to the water of the people of Madyan. This is when the righteous man said to him,

﴿لاَ تَخَفْ نَجَوْتَ مِنَ الْقَوْمِ الظَّـلِمِينَ﴾

(Fear you not. You have escaped from the people who are wrongdoers.) ﴿28:25﴾

﴿إِذْ تَمْشِى أُخْتُكَ فَتَقُولُ هَلْ أَدُلُّكُمْ عَلَى مَن يَكْفُلُهُ فَرَجَعْنَـكَ إِلَى أُمِّكَ كَى تَقَرَّ عَيْنُها وَلاَ تَحْزَنَ وَقَتَلْتَ نَفْساً فَنَجَّيْنَـكَ مِنَ الْغَمِّ وَفَتَنَّـكَ فُتُوناً فَلَبِثْتَ سِنِينَ فِى أَهْلِ مَدْيَنَ ثُمَّ جِئْتَ عَلَى قَدَرٍ يمُوسَى - وَاصْطَنَعْتُكَ لِنَفْسِى - اذْهَبْ أَنتَ وَأَخُوكَ بِـَايَـتِى وَلاَ تَنِيَا فِى ذِكْرِى - اذْهَبَآ إِلَى فِرْعَوْنَ إِنَّهُ طَغَى - فَقُولاَ لَهُ قَوْلاً لَّيِّناً لَّعَلَّهُ يَتَذَكَّرُ أَوْ يَخْشَى ﴾

(40. Then you stayed a number of years with the people of Madyan. Then you came here according to the fixed term which I ordained (for you), O Musa!) (41. And I have chosen you for Myself.) (42. Go you and your brother with My Ayat, and do not, you both, slacken and become weak in My remembrance.) (43. Go both of you to Fir`awn, verily, he has transgressed.) (44. And speak to him mildly, perhaps he may accept admonition or fear (Allah).)
