Allah tells us how He responded to His servant and Messenger Nuh, peace be upon him, when he prayed to Him against his people for their disbelief in him:

﴿فَدَعَا رَبَّهُ أَنُّى مَغْلُوبٌ فَانتَصِرْ ﴾

(Then he invoked his Lord (saying): "I have been overcome, so help (me)!'') ﴿54:10﴾

﴿وَقَالَ نُوحٌ رَّبِّ لاَ تَذَرْ عَلَى الاٌّرْضِ مِنَ الْكَـفِرِينَ دَيَّاراً - إِنَّكَ إِن تَذَرْهُمْ يُضِلُّواْ عِبَادَكَ وَلاَ يَلِدُواْ إِلاَّ فَاجِراً كَفَّاراً ﴾

(And Nuh said: "My Lord! Leave not any inhabitant of the disbelievers on the earth! If You leave them, they will mislead Your servants, and they will beget none but wicked disbelievers) ﴿71:26-27﴾. So Allah says here,

﴿إِذْ نَادَى مِن قَبْلُ فَاسْتَجَبْنَا لَهُ فَنَجَّيْنَـهُ وَأَهْلَهُ﴾

(And (remember) Nuh, when he cried (to Us) aforetime. We answered to his invocation and saved him and his family) meaning, those who believed with him, as Allah says elsewhere:

﴿وَأَهْلَكَ إِلاَّ مَن سَبَقَ عَلَيْهِ الْقَوْلُ وَمَنْ ءَامَنَ وَمَآ ءَامَنَ مَعَهُ إِلاَّ قَلِيلٌ﴾

(...and your family -- except him against whom the Word has already gone forth -- and those who believe. And none believed with him, except a few) ﴿11: 40﴾.

﴿مِنَ الْكَرْبِ الْعَظِيمِ﴾

(from the great dis- tress.) meaning, from difficulty, rejection and harm. For he remained among them for one thousand years less fifty, calling them to Allah, and no one had believed in him except for a few. His people were plotting against him and advising one another century after century, generation after generation, to oppose him.

﴿وَنَصَرْنَـهُ مِنَ الْقَوْمِ﴾

(We helped him against the people) means, `We saved him and helped him against the people,'

﴿الَّذِينَ كَذَّبُواْ بِـَايَـتِنَا إِنَّهُمْ كَانُواْ قَوْمَ سَوْءٍ فَأَغْرَقْنَـهُمْ أَجْمَعِينَ﴾

(who denied Our Ayat. Verily, they were a people given to evil. So We drowned them all.) meaning, Allah drowned them all, and not one of them was left on the face of the earth, as their Prophet had prayed would happen to them.

﴿وَدَاوُودَ وَسُلَيْمَـنَ إِذْ يَحْكُمَانِ فِى الْحَرْثِ إِذْ نَفَشَتْ فِيهِ غَنَمُ الْقَوْمِ وَكُنَّا لِحُكْمِهِمْ شَـهِدِينَ ﴾

﴿فَفَهَّمْنَـهَا سُلَيْمَـنَ وَكُلاًّ ءَاتَيْنَا حُكْماً وَعِلْماً وَسَخَّرْنَا مَعَ دَاوُودَ الْجِبَالَ يُسَبِّحْنَ وَالطَّيْرَ وَكُنَّا فَـعِلِينَ - وَعَلَّمْنَاهُ صَنْعَةَ لَبُوسٍ لَّكُمْ لِتُحْصِنَكُمْ مِّن بَأْسِكُمْ فَهَلْ أَنتُمْ شَـكِرُونَ - وَلِسُلَيْمَـنَ الرِّيحَ عَاصِفَةً تَجْرِى بِأَمْرِهِ إِلَى الاٌّرْضِ الَّتِى بَارَكْنَا فِيهَا وَكُنَّا بِكُلِّ شَىْءٍ عَـلِمِينَ - وَمِنَ الشَّيَـطِينِ مَن يَغُوصُونَ لَهُ وَيَعْمَلُونَ عَمَلاً دُونَ ذلِكَ وَكُنَّا لَهُمْ حَـفِظِينَ ﴾

(78. And (remember) Dawud and Sulayman, when they gave judgement in the case of the field in which the sheep of certain people had Nafashat; and We were witness to their judgement.) (79. And We made Sulayman to understand (the case); and to each of them We gave wisdom (Hukm) and knowledge. And We subjected the mountains and the birds to glorify Our praises along with Dawud. And it was We Who were the doer (of all these things).) (80. And We taught him the making of metal coats of mail (for battles), to protect you in your fighting. Are you then grateful) (81. And to Sulayman (We subjected) the wind strongly raging, running by his command towards the land which We had blessed. And of everything We are the All-Knower.) (82. And of the Shayatin were some who dived for him, and did other work besides that; and it was We Who guarded them.)
