✅ Answer: Please consider the following narrations:

1⃣ Imam Sadiq (peace be upon him) said: One day, while Amir al-Mu'minin (peace be upon him) was sitting with Muhammad bin Hanfiyyah, he suddenly said: 'O Muhammad! Bring me a vessel of water so I can perform Wudu for prayer!'

Then Muhammad brought a vessel of water to him. The Imam poured water on his left hand with his right hand and said:

بِسْمِ اللَّهِ وَ بِاللَّهِ وَ الْحَمْدُ لِلَّهِ الَّذِی جَعَلَ الْمَاءَ طَهُوراً وَ لَمْ یَجْعَلْهُ نَجِساً

He then performed Istinja (cleaning himself) and said:

اللَّهُمَّ حَصِّنْ فَرْجِی وَ أَعِفَّهُ وَ اسْتُرْ عَوْرَتِی وَ حَرِّمْنِی عَلَی النَّارِ

He then gargled and said:

اللَّهُمَّ لَقِّنِّی حُجَّتِی یَوْمَ أَلْقَاکَ وَ أَطْلِقْ لِسَانِی بِذِکْرِکَ وَ شُکْرِکَ

He then inhaled water through his nose and said:

اللَّهُمَّ لَا تُحَرِّمْ عَلَیَّ رِیحَ الْجَنَّةِ وَ اجْعَلْنِی مِمَّنْ یَشَمُّ رِیحَهَا وَ رَوْحَهَا وَ طِیبَهَا

He then washed his face and said:

اللَّهُمَّ بَیِّضْ وَجْهِی یَوْمَ تَسْوَدُّ فِیهِ الْوُجُوهُ وَ لَا تُسَوِّدْ وَجْهِی یَوْمَ تَبْیَضُّ فِیهِ الْوُجُوهُ

He then washed his right hand and said:

اللَّهُمَّ أَعْطِنِی کِتَابِی بِیَمِینِی وَ الْخُلْدَ فِی الْجِنَانِ بِیَسَارِی وَ حَاسِبْنِی حِسَاباً یَسِیراً

He then washed his left hand and said:

اللَّهُمَّ لَا تُعْطِنِی کِتَابِی بِیَسَارِی وَ لَا تَجْعَلْهَا مَغْلُولَةً إِلَی عُنُقِی وَ أَعُوذُ بِکَ رَبِّی مِنْ مُقَطَّعَاتِ النِّیرَانِ

He then wiped his head and said:

اللَّهُمَّ غَشِّنِی بِرَحْمَتِکَ وَ بَرَکَاتِکَ وَ عَفْوِکَ

He then, while wiping his feet, said:

اللَّهُمَّ ثَبِّتْنِی عَلَی الصِّرَاطِ یَوْمَ تَزِلُّ فِیهِ الْأَقْدَامُ وَ اجْعَلْ سَعْیِی فِیمَا یُرْضِیکَ عَنِّی یَا ذَا الْجَلَالِ وَ الْإِکْرَامِ

He then raised his head, looked at Muhammad, and said: 'O Muhammad! Whoever performs Wudu like mine and says what I have said, Allah, Blessed and Exalted, will create an angel from every drop of water, who will glorify and praise Allah and say Takbir, and Allah will write the reward for that person until the Day of Judgment!'

2⃣عَنْ أَبِی بَصِیرٍ وَ مُحَمَّدِ بْنِ مُسْلِمٍ عَنِ الصَّادِقِ عَنْ آبَائِهِ علیهم السلام قَالَ قَالَ أَمِیرُ الْمُؤْمِنِینَ علیه السلام: لَا یَتَوَضَّأُ الرَّجُلُ حَتَّی یُسَمِّیَ یَقُولُ قَبْلَ أَنْ یَمَسَّ الْمَاءَ بِسْمِ اللَّهِ اللَّهُمَّ اجْعَلْنِی مِنَ التَّوَّابِینَ وَ اجْعَلْنِی مِنَ الْمُتَطَهِّرِینَ فَإِذَا فَرَغَ مِنْ طَهُورِهِ قَالَ أَشْهَدُ أَنْ لَا إِلَهَ إِلَّا اللَّهُ وَحْدَهُ لَا شَرِیکَ لَهُ وَ أَشْهَدُ أَنَّ مُحَمَّداً عَبْدُهُ وَ رَسُولُهُ فَعِنْدَهَا یَسْتَحِقُّ الْمَغْفِرَةَ

📚 Al-Khisal, Vol. 2, p. 165.

Amir al-Mu'minin (peace be upon him) said: A person should not perform Wudu until they say 'Bismillah' (In the name of Allah). Before reaching the water, they should say:

بِسْمِ اللَّهِ اللَّهُمَّ اجْعَلْنِی مِنَ التَّوَّابِینَ وَ اجْعَلْنِی مِنَ الْمُتَطَهِّرِینَ

And when they complete their Wudu, they should say:

أَشْهَدُ أَنْ لَا إِلَهَ إِلَّا اللَّهُ وَحْدَهُ لَا شَرِیکَ لَهُ وَ أَشْهَدُ أَنَّ مُحَمَّداً عَبْدُهُ وَ رَسُولُهُ

Then, at that moment, they become deserving of forgiveness!

3⃣عَنِ الْعَلَاءِ بْنِ الْفُضَیْلِ عَنْ أَبِی عَبْدِ اللَّهِ علیه السلام قَالَ: إِذَا تَوَضَّأَ أَحَدُکُمْ وَ لَمْ یُسَمِّ کَانَ لِلشَّیْطَانِ فِی وُضُوئِهِ شِرْکٌ فَإِنْ أَکَلَ أَوْ شَرِبَ أَوْ لَبِسَ وَ کُلُّ شَیْءٍ صَنَعَهُ یَنْبَغِی لَهُ أَنْ یُسَمِّیَ عَلَیْهِ وَ إِنْ لَمْ یَفْعَلْ کَانَ لِلشَّیْطَانِ فِیهِ شِرْکٌ

📚 Al-Mahasin, p. 430

Imam Sadiq (peace be upon him) said: When one of you performs Wudu and does not say 'Bismillah,' Satan shares in his Wudu. So, if he eats, drinks, or wears something, or does any other action, it is proper to say 'Bismillah,' and if he does not do so, Satan shares in that action!

4⃣قَالَ الْبَاقِرُ مَنْ قَرَأَ عَلَى أَثَرِ الْوُضُوءِ آيَةَ الْكُرْسِيِّ مَرَّةً أَعْطَاهُ اللَّهُ تَعَالَى ثَوَابَ أَرْبَعِينَ عَاماً وَ رَفَعَ لَهُ أَرْبَعِينَ دَرَجَةً وَ زَوَّجَهُ اللَّهُ تَعَالَى أَرْبَعِينَ حَوْرَاءَ

📚 Mustadrak al-Wasa'il, Vol. 1, p. 321

Imam Baqir (peace be upon him) said: Whoever recites Ayat al-Kursi once after performing Wudu, Allah, the Almighty, will reward him with the reward of forty years, raise him forty levels, and marry him to forty Hoor al-Ayn (women of Paradise)!

اللَّهُمَّ صَلِّ عَلَی مُحَمَّدٍ وَ آلِ مُحَمَّدٍ وَ عَجِّلْ لِوَلِیِّکَ الْفَرَجَ وَ الْعَافِیَةَ وَ النَّصْر
