This is how good is repaid.

Musa and Harun, rescued and remembered

What Musa and Harun received
Musa and Harununder Fir'awn's cruelty
were given
rescuefrom the great distress
the clear Bookand the straight path
a good namepraised by later generations
Why it happened
luckthings just worked out
a patternthis is how Allah repays good

Musa and Harun lived under Fir'awn, who killed the sons of their people and forced them into the lowest work. Allah saved them, gave them the clear Scripture, and left them a good name after they died. Then He says this is not a one-off: it is how He treats those who do good.

You stay honest at a job where cutting corners is normal. You keep visiting a difficult parent when nobody notices. It feels like it goes nowhere. This verse says it is going somewhere. Good is not lost in the system. It is repaid, by a Lord who keeps a pattern.

Doing good is nice, but it rarely changes how things turn out.

Good done for Allah sits inside a pattern of repayment He has promised to keep.

Try this

Do one quiet good thing today that nobody will thank you for, and leave the repayment to Allah.

And, indeed We gave Our grace to Musa and Harun (114)And We saved them and their people from the great distress (115)And helped them, so that they became the victors (116)And We gave them the clear Scripture (117)And guided them to the right path (118)And We left for them among the later generations (119)"Salam (peace!) be upon Musa and Harun! (120)Verily, thus do We reward the doers of good (121)Verily, they were two of Our believing servants (122)

Musa and Harun

Allah tells us how He blessed Musa and Harun with prophethood and how He saved them, along with those who believed, from the oppression of Fir'awn and his people, who had persecuted them by killing their sons and sparing their women, and by forcing them to do the most menial tasks, then ultimately He caused them to prevail over them and to seize their lands and their wealth and all that they had spent their entire lives amassing. Then Allah revealed to Musa the Clear and Mighty Book, which is the Tawrah, as Allah says:

وَلَقَدْ آتَيْنَا مُوسَىٰ وَهَارُونَ الْفُرْقَانَ وَضِيَاءً

(And indeed We granted to Musa and Harun the criterion (of right and wrong), and a shining light)(21:48). And Allah says here:

وَآتَيْنَاهُمَا الْكِتَابَ الْمُسْتَبِينَ - وَهَدَيْنَاهُمَا الصِّرَاطَ الْمُسْتَقِيمَ

(And We gave them the clear Scripture; and guided them to the right path.) meaning, with regard to words and deeds.

وَتَرَكْنَا عَلَيْهِمَا فِي الْآخِرِينَ

(And We left for them among the later generations.) means, that after they died they would be mentioned in good terms and spoken of highly. Then Allah explain this further:

سَلَامٌ عَلَىٰ مُوسَىٰ وَهَارُونَ - إِنَّا كَذَٰلِكَ نَجْزِي الْمُحْسِنِينَ - إِنَّهُمَا مِنْ عِبَادِنَا الْمُؤْمِنِينَ

(Salam (peace!) be upon Musa and Harun! Verily, thus do We reward the doers of good. Verily, they were two of Our believing servants.)
