Hadith about the Covenant of Souls (Alastu bi Rabbikum):

Allah gathered all the souls before creating our bodies and asked:
“Am I not your Lord?”
They replied: “Yes, we testify.”
— Surah Al-A’raf, Chapter 7, Verse 172
(Supported by Hadith in Musnad Ahmad, Sunan al-Tirmidhi)

📖 This event is referred to as the Day of the Covenant (Yaum-e-Alast) — where every soul testified to Allah’s Lordship before being sent into this world.

The Prophet ﷺ explained this moment in several narrations, including:

“Allah took the covenant from Adam’s offspring in Na’man (i.e. Arafah), and brought forth from his loin every soul He would create until the Day of Resurrection…”
— Musnad Ahmad, Hadith 2455
