✅ Answer: Pay attention to one of the narrations on this matter:

قَالَ الصَّادِقُ وَ لَرُبَّمَا تَرَکَ بَعْضُ شِیعَتِنَا فِی افْتِتَاحِ أَمْرِهِ بِسْمِ اللَّهِ الرَّحْمنِ الرَّحِیمِ فَیَمْتَحِنُهُ اللَّهُ بِمَکْرُوهٍ لِیُنَبَّهَ عَلَی شُکْرِ اللَّهِ وَ الثَّنَاءِ عَلَیْهِ وَ یُمْحَقَ وَصْمَةُ تَقْصِیرِهِ عِنْدَ تَرْکِهِ قَوْلَ بِسْمِ اللَّهِ الرحمن الرحیم

📚 *Tawhid* by Saduq, p. 231

Translation: Imam Hassan al-Askari (AS) said in a narration: Imam al-Sadiq (AS) said: It is possible that one of our Shi'ah might neglect saying 'Bismillah al-Rahman al-Rahim' at the beginning of their task, so Allah tests them with some difficulty or misfortune to awaken them to thank Allah and praise Him. This is to eliminate the defect and shortcoming caused by their neglect of saying 'Bismillah al-Rahman al-Rahim'.

✅ It is unlikely that the Shi'ah of Amir al-Mu'minin (AS) would deliberately neglect saying 'Bismillah al-Rahman al-Rahim' at the beginning of all their tasks. As for cases where it happens due to forgetfulness or haste, we follow the following hadith to protect ourselves from its consequences:

عَنْ مُحَمَّدِ بْنِ مُسْلِمٍ قَالَ قَالَ أَبُو عَبْدِ اللَّهِ إِنَّ عَلِیَّ بْنَ الْحُسَیْنِ کَانَ إِذَا أَصْبَحَ قَالَ- أَبْتَدِئُ یَوْمِی هَذَا بَیْنَ یَدَیْ نِسْیَانِی وَ عَجَلَتِی بِسْمِ اللَّهِ وَ مَا شَاءَ اللَّهُ فَإِذَا فَعَلَ ذَلِکَ الْعَبْدُ أَجْزَأَهُ مِمَّا نَسِیَ فِی یَوْمِهِ

📚 *Kafi*, Vol. 2, p. 523

Translation: Imam al-Sadiq (AS) said: Indeed, when Imam al-Sajjad (AS) would start his day, he would say:

أَبْتَدِئُ یَوْمِی هَذَا بَیْنَ یَدَیْ نِسْیَانِی وَ عَجَلَتِی بِسْمِ اللَّهِ وَ مَا شَاءَ اللَّهُ

Translation: 'I begin this day in the name of Allah and as Allah wills, to protect me from forgetfulness and haste.'

So when a servant does this, it suffices them for the things they forget throughout the day.

✅ Explanation: This means that when one says this phrase at the beginning of the day, it will suffice them for any tasks they forget to begin with 'Bismillah al-Rahman al-Rahim' throughout the day.

Note: Also pay attention to the following narration:

عَنْ أَبِیهِ عَنْ مُحَمَّدِ بْنِ سِنَانٍ عَنِ الْعَلَاءِ بْنِ الْفُضَیْلِ عَنْ أَبِی عَبْدِ اللَّهِ قَالَ إِذَا تَوَضَّأَ أَحَدُکُمْ وَ لَمْ یُسَمِّ کَانَ لِلشَّیْطَانِ فِی وُضُوئِهِ شِرْکٌ وَ إِنْ أَکَلَ أَوْ شَرِبَ أَوْ لَبِسَ وَ کُلَّ شَیْ ءٍ صَنَعَهُ یَنْبَغِی لَهُ أَنْ یُسَمِّیَ عَلَیْهِ فَإِنْ لَمْ یَفْعَلْ کَانَ لِلشَّیْطَانِ فِیهِ شِرْکٌ

📚 *Mahasin*, Vol. 2, p. 4

Translation: Imam al-Sadiq (AS) said: When one of you performs ablution and does not say 'Bismillah', Satan becomes a partner in their ablution. Likewise, if they eat, drink, or wear clothing, and any task they perform, it is appropriate for them to say 'Bismillah'. If they do not, Satan becomes a partner in that action.
