✅Answer: Verse 56 of Surah al-Ahzab is this:

إِنَّ اللَّهَ وَمَلَائِکَتَهُ یُصَلُّونَ عَلَی النَّبِیِّ ۚ یَا أَیُّهَا الَّذِینَ آمَنُوا صَلُّوا عَلَیْهِ وَسَلِّمُوا تَسْلِیمًا (۵۶)

Translation: Indeed, God and His angels send blessings upon the Prophet. O you who have believed, send blessings upon him and submit to his command completely.

✅The beautiful verse above has important interpretations that are mentioned in their place. However, as one of the post-prayer supplications, it has also been mentioned, and its place and manner are specified in the following two narrations:

1 عَنْ سَعْدِ بْنِ عَبْدِ اللَّهِ عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنْ أَبِیهِ عَنْ أَبِی الْمُغِیرَةِ قَالَ سَمِعْتُ أَبَا الْحَسَنِ علیه السلام یَقُولُ: مَنْ قَالَ فِی دُبُرِ صَلَاةِ الصُّبْحِ وَ صَلَاةِ الْمَغْرِبِ قَبْلَ أَنْ یَثْنِیَ رِجْلَیْهِ أَوْ یُکَلِّمَ أَحَداً- إِنَّ اللَّهَ وَ مَلائِکَتَهُ یُصَلُّونَ عَلَی النَّبِیِّ یا أَیُّهَا الَّذِینَ آمَنُوا صَلُّوا عَلَیْهِ وَ سَلِّمُوا تَسْلِیماً اللَّهُمَّ صَلِّ عَلَی مُحَمَّدٍ وَ ذُرِّیَّتِهِ قَضَی اللَّهُ لَهُ مِائَةَ حَاجَةٍ سَبْعِینَ فِی الدُّنْیَا وَ ثَلَاثِینَ فِی الْآخِرَةِ قَالَ قُلْتُ لَهُ مَا مَعْنَی صَلَاةِ اللَّهِ وَ صَلَاةِ مَلَائِکَتِهِ وَ صَلَاةِ الْمُؤْمِنِینَ قَالَ صَلَاةُ اللَّهِ رَحْمَةٌ مِنَ اللَّهِ وَ صَلَاةُ مَلَائِکَتِهِ تَزْکِیَةٌ مِنْهُمْ لَهُ وَ صَلَاةُ الْمُؤْمِنِینَ دُعَاءٌ مِنْهُمْ لَهُ...

📚 Thawab al-A'mal, p. 141

Abu Mughirah says: I heard Abu al-Hasan (peace be upon him) saying: The one who says after the Fajr prayer and the Maghrib prayer, before moving his feet or speaking to anyone:

إِنَّ اللَّهَ وَ مَلائِکَتَهُ یُصَلُّونَ عَلَی النَّبِیِّ یا أَیُّهَا الَّذِینَ آمَنُوا صَلُّوا عَلَیْهِ وَ سَلِّمُوا تَسْلِیماً اللَّهُمَّ صَلِّ عَلَی مُحَمَّدٍ وَ ذُرِّیَّتِهِ

God will fulfill 100 of his needs: 70 of them in this world and 30 of them in the Hereafter!

I said: What is the meaning of God's blessings, His angels' blessings, and the believers' blessings? He said: The prayer and blessing of God is a mercy from Him, and the prayer and blessing of His angels is a purification from them for him, and the prayer and blessing of the believers is a supplication from them for him.

2 عَنِ الْحَسَنِ بْنِ مَحْبُوبٍ عَنْ مُعَاوِیَةَ بْنِ عَمَّارٍ عَنْ أَبِی عَبْدِ اللَّهِ علیه السلام قَالَ: مَنْ قَالَ بَعْدَ صَلَاةِ الْفَجْرِ وَ بَعْدَ صَلَاةِ الْمَغْرِبِ قَبْلَ أَنْ یَثْنِیَ رِجْلَهُ أَوْ یُکَلِّمَ أَحَداً- إِنَّ اللَّهَ وَ مَلائِکَتَهُ یُصَلُّونَ عَلَی النَّبِیِّ یا أَیُّهَا الَّذِینَ آمَنُوا صَلُّوا عَلَیْهِ وَ سَلِّمُوا تَسْلِیماً اللَّهُمَّ صَلِّ عَلَی مُحَمَّدٍ النَّبِیِّ وَ عَلَی ذُرِّیَّتِهِ وَ عَلَی أَهْلِ بَیْتِهِ مَرَّةً وَاحِدَةً قَضَی اللَّهُ تَعَالَی لَهُ مِائَةَ حَاجَةٍ سَبْعِینَ مِنْهَا لِلْآخِرَةِ وَ ثَلَاثِینَ لِلدُّنْیَا

📚 Falah al-Sa'il, p. 230

Imam al-Sadiq (peace be upon him) said: The one who says once after the Fajr prayer and the Maghrib prayer, before moving his feet or speaking to anyone:

إِنَّ اللَّهَ وَ مَلائِکَتَهُ یُصَلُّونَ عَلَی النَّبِیِّ یا أَیُّهَا الَّذِینَ آمَنُوا صَلُّوا عَلَیْهِ وَ سَلِّمُوا تَسْلِیماً اللَّهُمَّ صَلِّ عَلَی مُحَمَّدٍ النَّبِیِّ وَ عَلَی ذُرِّیَّتِهِ وَ عَلَی أَهْلِ بَیْتِهِ

God will fulfill 100 of his needs, 70 of them for the Hereafter and 30 of them for this world.

✅It is observed that the noble verse 56 of Surah al-Ahzab, along with the continuation of a brief salawat, is specifically recited after the Fajr and Maghrib prayers. Of course, the type of salawat in these two narrations has a slight difference, and also its reward is different in these two narrations. In the narration of Thawab al-A'mal, it is 70 needs from this world and 30 needs for the Hereafter, but in the narration of Falah al-Sa'il, it is the opposite.

✅It is observed that this verse, along with the salawat after it, is specific to the Fajr and Maghrib prayers.

However, the above verse, along with another specific salawat and supplication, is also said after the tasbihat of Lady Zahra (peace be upon her), whose narration was mentioned in question 375 of the channel. Please refer to it for more information: 👇
