I would like to locate the source of some ahadith:
- The Prophet (S) used to say: “On the Day of Resurrection, I will identify my ummah by the mark of prostration that they have on their foreheads.”
- That portion of the earth on which prostration was made will testify to the devotion of man on the Day of Resurrection.
- And even in the world, a radiant point connect it to the heavens.
(These are three narrations of one hadith, I think)
