Understanding the 'Days of Allah' in Tradition

Hawzah News Agency- Imam Baqir(a.s) said:

أَیَّامُ اللَّهِ عَزَّ وَ جَلَّ ثَلَاثَهٌ یَوْمَ یَقُومُ الْقَائِمُ وَ یَوْمَ الْکَرَّهِ وَ یَوْمَ الْقِیَامَهِ.

The Days of Allah—the Almighty and Majestic—are three: the day the Qa’im (Imam Mahdi a.s) rises, the day of the Return (al-Raj‘ah), and the Day of Resurrection.

Al-Khisal,Book 3,Hadith 75
