1⃣ عَنِ ابْنِ سِنَانٍ عَنْ أَبِی عَبْدِ اللَّهِ فِی حَدِیثٍ قَالَ فِی یَوْمِ عَرَفَةَ یَجْتَمِعُونَ بِغَیْرِ إِمَامٍ فِی الْأَمْصَارِ یَدْعُونَ اللَّهَ عَزَّ وَ جَلَّ

📚 Al-Tahdhīb, Volume 3, Page 136

Imam Sadiq (peace be upon him) said in a narration: On the Day of Arafah, people gather in other cities without an Imam and call upon Allah, the Mighty and Majestic.

✅ Other narrations also discuss gathering for prayers at all times, including:

2⃣عَنْ عَلِیِّ بْنِ إِبْرَاهِیمَ عَنْ أَبِیهِ عَنْ عَلِیِّ بْنِ مَعْبَدٍ عَنْ عُبَیْدِ اللَّهِ بْنِ عَبْدِ اللَّهِ الْوَاسِطِیِّ عَنْ دُرُسْتَ بْنِ أَبِی مَنْصُورٍ عَنْ أَبِی خَالِدٍ قَالَ قَالَ أَبُو عَبْدِ اللَّهِ مَا مِنْ رَهْطٍ أَرْبَعِینَ رَجُلًا اجْتَمَعُوا فَدَعَوُا اللَّهَ عَزَّ وَ جَلَّ فِی أَمْرٍ إِلَّا اسْتَجَابَ لَهُمْ فَإِنْ لَمْ یَکُونُوا أَرْبَعِینَ فَأَرْبَعَةٌ یَدْعُونَ اللَّهَ عَزَّ وَ جَلَّ عَشْرَ مَرَّاتٍ إِلَّا اسْتَجَابَ اللَّهُ لَهُمْ فَإِنْ لَمْ یَکُونُوا أَرْبَعَةً فَوَاحِدٌ یَدْعُو اللَّهَ أَرْبَعِینَ مَرَّةً فَیَسْتَجِیبُ اللَّهُ الْعَزِیزُ الْجَبَّارُ لَهُ

📚 Al-Kafi, Volume 2, Page 487

Imam Sadiq (peace be upon him) said: No group of forty people gather together to pray for any matter except that Allah answers their prayers. If there are not forty, then four people should pray ten times, and Allah will answer their prayer. If there are not four, then one person should pray forty times, and Allah, the Almighty, will answer their prayer.

Note:

✅ On the Day of Arafah, let us not forget to pray for the hastening of the reappearance of our Master.

✅ On the Day of Arafah, let us not neglect the unparalleled prayer of 47 from Sahifa Sajjadiya.

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