I asked Muhajid regarding the prostration in Surat Saʿd. He said, "Ibn ʿAbbas was asked the same question and he said, 'Those are they (the prophets) whom Allah had Guided. So follow their guidance." (6.90) Ibn ʿAbbas used to perform a prostration (on reading this Sura).  

{أُولَئِكَ الَّذِينَ هَدَى اللَّهُ فَبِهُدَاهُمُ اقْتَدِهْ} وَكَانَ ابْنُ عَبَّاسٍ يَسْجُدُ فِيهَا  

I asked Mujahid regarding the prostration in Surat Saʿd. He said, "I asked Ibn ʿAbbas, 'What evidence makes you prostrate?' He said, "Don't you recite:--'And among his progeny, David and Solomon..(6.84). Those are they whom Allah had guided. So follow their guidance.' (6.90) So David was the one of those prophets whom Prophet (Muhammad) was ordered to follow. David prostrated, so Messenger of Allah ﷺ (Muhammad) performed this prostration too.'  

أَوَمَا تَقْرَأُ {وَمِنْ ذُرِّيَّتِهِ دَاوُدَ وَسُلَيْمَانَ} {أُولَئِكَ الَّذِينَ هَدَى اللَّهُ فَبِهُدَاهُمُ اقْتَدِهْ} فَكَانَ دَاوُدُ مِمَّنْ أُمِرَ نَبِيُّكُمْ ﷺ أَنْ يَقْتَدِيَ بِهِ فَسَجَدَهَا رَسُولُ اللَّهِ ﷺ {عُجَابٌ} عَجِيبٌ الْقِطُّ الصَّحِيفَةُ هُوَ هَا هُنَا صَحِيفَةُ الْحَسَنَاتِ وَقَالَ مُجَاهِدٌ {فِي عِزَّةٍ} مُعَازِّينَ {الْمِلَّةِ الآخِرَةِ} مِلَّةُ قُرَيْشٍ الاِخْتِلاَقُ الْكَذِبُ الأَسْبَابُ طُرُقُ السَّمَاءِ فِي أَبْوَابِهَا {جُنْدٌ مَا هُنَالِكَ مَهْزُومٌ} يَعْنِي قُرَيْشًا {أُولَئِكَ الأَحْزَابُ} الْقُرُونُ الْمَاضِيَةُ {فَوَاقٍ} رُجُوعٍ {قِطَّنَا} عَذَابَنَا {اتَّخَذْنَاهُمْ سُخْرِيًّا} أَحَطْنَا بِهِمْ أَتْرَابٌ أَمْثَالٌ وَقَالَ ابْنُ عَبَّاسٍ الأَيْدُ الْقُوَّةُ فِي الْعِبَادَةِ الأَبْصَارُ الْبَصَرُ فِي أَمْرِ اللَّهِ {حُبَّ الْخَيْرِ عَنْ ذِكْرِ رَبِّي} مِنْ ذِكْرٍ {طَفِقَ مَسْحًا} يَمْسَحُ أَعْرَافَ الْخَيْلِ وَعَرَاقِيبَهَا {الأَصْفَادِ} الْوَثَاقِ  

The Prophet ﷺ said, "Last night a demon from the Jinns came to me (or the Prophet ﷺ said, a similar sentence) to disturb my prayer, but Allah gave me the power to overcome him. I intended to tie him to one of the pillars of the mosque till the morning so that all of you could see him, but then I remembered the Statement of my brother Solomon:--'My Lord! Forgive me and bestow on me a kingdom such as shall not belong to any other after me.' (38.35) The narrator added: Then he (the Prophet) dismissed him, rejected.  

عَنِ النَّبِيِّ ﷺ قَالَ إِنَّ عِفْرِيتًا مِنَ الْجِنِّ تَفَلَّتَ عَلَىَّ الْبَارِحَةَ أَوْ كَلِمَةً نَحْوَهَا لِيَقْطَعَ عَلَىَّ الصَّلاَةَ فَأَمْكَنَنِي اللَّهُ مِنْهُ وَأَرَدْتُ أَنْ أَرْبِطَهُ إِلَى سَارِيَةٍ مِنْ سَوَارِي الْمَسْجِدِ حَتَّى تُصْبِحُوا وَتَنْظُرُوا إِلَيْهِ كُلُّكُمْ فَذَكَرْتُ قَوْلَ أَخِي سُلَيْمَانَ رَبِّ هَبْ لِي مُلْكًا لاَ يَنْبَغِي لأَحَدٍ مِنْ بَعْدِي قَالَ رَوْحٌ فَرَدَّهُ خَاسِئًا  

We came upon ʿAbdullah bin Masʿud and he said "O people! If somebody knows something, he can say it, but if he does not know it, he should say, "Allah knows better,' for it is a sign of having knowledge to say about something which one does not know, 'Allah knows better.' Allah said to His Prophet: 'Say (O Muhammad ! ) No wage do I ask of You for this (Qur'an) nor am I one of the pretenders (a person who pretends things which do not exist).' (38.86) Now I will tell you about Ad- Dukhan (the smoke), Messenger of Allah ﷺ invited the Quraish to embrace Islam, but they delayed their response. So he said, "O Allah! Help me against them by sending on them seven years of famine similar to the seven years of famine of Joseph." So the famine year overtook them and everything was destroyed till they ate dead animals and skins. People started imagining to see smoke between them and the sky because of severe hunger. Allah said: 'Then watch you for the Day that the sky will bring forth a kind of smoke plainly visible, covering the people. . . This is painful torment.' (44.10-11) (So they invoked Allah) "Our Lord! Remove the punishment from us really we are believers." How can there be an (effectual) reminder for them when an Apostle, explaining things clearly, has already come to them? Then they had turned away from him and said: 'One taught (by a human being), a madman?' 'We shall indeed remove punishment for a while, but truly, you will revert (to disbelief).' (44.12-15) Will the punishment be removed on the Day of Resurrection?" ʿAbdullah added, "The punishment was removed from them for a while but they reverted to disbelief, so Allah destroyed them on the Day of Badr. Allah said: 'The day We shall seize you with a mighty grasp. We will indeed (then) exact retribution." (44.16)
