Regarding the prohibition of seeking worldly affairs on certain days, we present the following narrations for you to reflect on and derive your conclusion, InshaAllah.

1⃣عَنْ أَبِی الْحَسَنِ عَلِیِّ بْنِ مُوسَی الرِّضَا قَالَ مَنْ تَرَکَ السَّعْیَ فِی حَوَائِجِهِ یَوْمَ عَاشُورَاءَ قَضَی اللَّهُ لَهُ حَوَائِجَ الدُّنْیَا وَ الْآخِرَةِ وَ مَنْ کَانَ یَوْمُ عَاشُورَاءَ یَوْمَ مُصِیبَتِهِ وَ حُزْنِهِ وَ بُکَائِهِ یَجْعَلُ اللَّهُ عَزَّ وَ جَلَّ یَوْمَ الْقِیَامَةِ یَوْمَ فَرَحِهِ وَ سُرُورِهِ وَ قَرَّتْ بِنَا فِی الْجِنَانِ عَیْنُهُ وَ مَنْ سَمَّی یَوْمَ عَاشُورَاءَ یَوْمَ بَرَکَةٍ وَ ادَّخَرَ لِمَنْزِلِهِ فِیهِ شَیْئاً لَمْ یُبَارَکْ لَهُ فِیمَا ادَّخَرَ وَ حُشِرَ یَوْمَ الْقِیَامَةِ مَعَ یَزِیدَ وَ عُبَیْدِ اللَّهِ بْنِ زِیَادٍ وَ عُمَرَ بْنِ سَعْدٍ لَعَنَهُمُ اللَّهُ إِلَی أَسْفَلِ دَرْکٍ مِنَ النَّارِ

📚Amali Sheikh Saduq, p. 129

Translation:

Imam Reza (AS) said: 'Whoever refrains from seeking his worldly needs and work on the day of Ashura, Allah will fulfill his needs in this world and the Hereafter. Whoever makes Ashura a day of grief, sorrow, and tears, Allah will make the Day of Judgment a day of joy and happiness for him, and his eyes will be delighted with us in Paradise. But whoever calls Ashura a day of blessing and stores something for his household on this day, there will be no blessing in what he has stored, and on the Day of Judgment, he will be gathered in the lowest level of Hell with Yazid, Ubaydullah ibn Ziyad, and Umar ibn Sa'd (may Allah curse them all).'

2⃣قال أبو جعفر الباقر فی حدیث... وَ إِنِ اسْتَطَعْتَ أَنْ لَا تَنْشُرَ یَوْمَکَ فِی حَاجَةٍ فَافْعَلْ فَإِنَّهُ یَوْمُ نَحْسٍ لَا تُقْضَی فِیهِ حَاجَةُ مُؤْمِنٍ وَ إِنْ قُضِیَتْ لَمْ یُبَارَکُ لَهُ فِیهَا وَ لَا یَرَی فِیهَا رُشْداً وَ لَا یَدَّخِرَنَّ أَحَدُکُمْ لِمَنْزِلِهِ فِیهِ شَیْئاً

📚Kamil al-Ziyarat, p. 175

Translation:

Imam Baqir (AS) said in a narration: 'If you can avoid seeking your work and needs on the day of Ashura, then do so, for it is an ominous and inauspicious day, and a believer’s need is not fulfilled on this day. Even if it is fulfilled, it will have no blessing, growth, or increase. No one should store anything for their household on this day, for if they do, there will be no blessing in it, nor in their family (wife and children).'

✅Thus, by refraining from work and making Ashura a day of mourning, crying, and grief, one fulfills their religious duty, InshaAllah.

3⃣مُحَمَّدُ بْنُ یَعْقُوبَ عَنْ عِدَّةٍ مِنْ أَصْحَابِنَا عَنْ سَهْلِ بْنِ زِیَادٍ عَنْ مُحَمَّدِ بْنِ الْحَسَنِ بْنِ شَمُّونٍ عَنْ عَبْدِ اللَّهِ بْنِ عَبْدِ الرَّحْمَنِ الْأَصَمِّ عَنْ مِسْمَعِ بْنِ عَبْدِ الْمَلِکِ عَنْ أَبِی عَبْدِ اللَّهِ قَالَ الصُّنَّاعُ إِذَا سَهِرُوا اللَّیْلَ کُلَّهُ فَهُوَ سُحْتٌ

✅Note:

Regarding working throughout the night to earn a livelihood, consider the following two narrations:

4⃣عَنْ عَلِیِّ بْنِ مُحَمَّدٍ عَنْ صَالِحِ بْنِ أَبِی حَمَّادٍ عَنْ غَیْرِ وَاحِدٍ عَنِ الشَّعِیرِیِّ عَنْ أَبِی عَبْدِ اللَّهِ قَالَ مَنْ بَاتَ سَاهِراً فِی کَسْبٍ وَ لَمْ یُعْطِ الْعَیْنَ حَظَّهَا مِنَ النَّوْمِ فَکَسْبُهُ ذَلِکَ حَرَامٌ

📚Al-Kafi, Vol. 5, p. 127

Translation:

Imam Sadiq (AS) said: 'If craftsmen stay awake the entire night (for work), their earnings are illicit and forbidden.'
