✅Answer: Please pay attention to the following narrations:

1 عَنْ سَعْدَانَ عَنْ عَبْدِ اللَّهِ بْنِ سِنَانٍ عَنْ أَبِي عَبْدِ اللَّهِ قَالَ: مَنْ صَلَّى أَرْبَعَ رَكَعَاتٍ يَقْرَأُ فِي كُلِّ رَكْعَةٍ قُلْ هُوَ اللَّهُ أَحَدٌ خَمْسِينَ مَرَّةً لَمْ يَنْفَتِلْ وَ بَيْنَهُ وَ بَيْنَ اللَّهِ ذَنْبٌ.

📚 Al-Kafi, Vol. 3, p. 468

Imam Al-Sadiq (peace be upon him) said: 'Whoever performs four rak'ahs of prayer and recites Surah Qul Huwa Allahu Ahad (The Unity) fifty times in each rak'ah, will not finish the prayer with any sin remaining between him and Allah!'

2 عَنْ أَبِي بَصِيرٍ عَنْ أَبِي عَبْدِ اللَّهِ قَالَ مَنْ صَلَّى أَرْبَعَ رَكَعَاتٍ بِمِائَتَيْ مَرَّةٍ قُلْ هُوَ اللَّهُ أَحَدٌ فِي كُلِّ رَكْعَةٍ خَمْسِينَ مَرَّةً لَمْ يَنْتَفلْ وَ بَيْنَهُ وَ بَيْنَ اللَّهِ عَزَّ وَ جَلَّ ذَنْبٌ إِلَّا غُفِرَ لَهُ

📚 Amali al-Saduq, p. 87

📚 Al-Bihar, Vol. 91, p. 171, Hadith 2

Imam Al-Sadiq (peace be upon him) said: 'Whoever performs four rak'ahs of prayer with 200 recitations of Qul Huwa Allahu Ahad, will not turn away from the prayer with any sin between him and Allah, the Almighty and Glorious, except that it will be forgiven!'

3 مُحَمَّدُ بْنُ الْحَسَنِ فِي الْمِصْبَاحِ قَالَ رُوِيَ عَنِ الصَّادِقِ جَعْفَرِ بْنِ مُحَمَّدٍ أَنَّهُ قَالَ: مَنْ صَلَّى مِنْكُمْ أَرْبَعَ رَكَعَاتٍ صَلَاةَ أَمِيرِ الْمُؤْمِنِينَ خَرَجَ مِنْ ذُنُوبِهِ كَيَوْمَ وَلَدَتْهُ أُمُّهُ وَ قُضِيَتْ حَوَائِجُهُ يَقْرَأُ فِي كُلِّ رَكْعَةٍ الْحَمْدَ مَرَّةً وَ خَمْسِينَ مَرَّةً قُلْ هُوَ اللَّهُ أَحَدٌ

📚 Misbah al-Mutahajjid, p. 256

Imam Al-Sadiq (peace be upon him) said: 'Any of you who performs the four rak'ahs of the prayer of Amir al-Mu'minin (peace be upon him) will emerge from his sins as on the day his mother gave birth to him, and his needs will be fulfilled. In each rak'ah, he recites Surah Al-Hamd once and Surah Qul Huwa Allahu Ahad (i.e., Surah Al-Tawhid) fifty times!'

4 عَنْ مُحَمَّدِ بْنِ سِنَانٍ عَنِ الْمُفَضَّلِ بْنِ عُمَرَ عَنْ أَبِي عَبْدِ اللَّهِ أَنَّهُ قَالَ في حديث

تُصَلِّي فِي كُلِّ يَوْمِ جُمُعَةٍ فِي شَهْرِ رَمَضَانَ أَرْبَعَ رَكَعَاتٍ لِأَمِيرِ الْمُؤْمِنِينَ... فَأَمَّا صَلَاةُ أَمِيرِ الْمُؤْمِنِينَ فَإِنَّهُ يُقْرَأُ فِيهَا بِالْحَمْدِ فِي كُلِّ رَكْعَةٍ وَ خَمْسِينَ مَرَّةً قُلْ هُوَ اللَّهُ أَحَدٌ...

📚 Al-Tahdhib, Vol. 3, p. 66

Imam Al-Sadiq (peace be upon him) said in a hadith: 'On every Friday of Ramadan, you perform the four rak'ahs of the prayer of Amir al-Mu'minin...' until he said: 'As for the prayer of Amir al-Mu'minin, in each rak'ah of it, Surah Al-Hamd is recited once and Qul Huwa Allahu Ahad fifty times...'

✅ Based on the above narrations, it is clear that the prayer of Amir al-Mu'minin (peace be upon him) consists of four rak'ahs, in each of which Surah Al-Hamd is recited once and Surah Al-Tawhid 50 times. Among its benefits are the forgiveness of sins and the fulfillment of needs.

✅ It is important to note that all voluntary prayers (nafilah) are two rak'ahs, so this prayer is also performed as two separate two-rak'ah prayers. You can study the narrations related to this topic in the following link:
