Signs of Prophethood ﷺ

The noble chest was split four times

The first of the perceptible signs of prophethood was the splitting of his noble chest ﷺ, and this happened to him four times: the first was during his time with Halimah al‑Sa'diyah when he was four years old, according to the authentic report. The second was when he was ten years old. The third was at the coming of revelation when he was informed of prophethood. The fourth was on the night of al‑Isrā' and al‑Miʿrāj, as reported in the Two Sahihs.

The first time: with Halimah al‑Sa'diyah — when he was four years old
The second time: when he was ten years old
The third time: at the coming of revelation and the beginning of prophethood
The fourth time: the night of al‑Isrā' and al‑Miʿrāj — reported in the Two Sahihs

Seal of Prophethood

Among the signs of prophethood is the seal of prophethood. The most commonly reported description is that it was like a pigeon's egg, and that it was a small raised piece of flesh — that is, elevated — on his back at the hollow of his left shoulder; it shone with light, was clothed in awe, and exhaled the wird. The People of the Book recognized this seal among the descriptions of the Prophet ﷺ in their books.

On his back ﷺ at the hollow of his left shoulder
Like a pigeon's egg — a small raised elevated piece of flesh
It radiated light, exhaled the wird, and was accompanied by awe
The People of the Book knew it among the descriptions of the Prophet in their books

The true vision and other signs

Among the signs of prophethood is the true vision; the Prophet ﷺ would not see a vision except that it came like the break of dawn. He would hear the tasbih and would be found with the forenoon and the light. Stones and trees would greet him, and a cloud would shade him during heat and travel.

The true vision: it would always come like the break of dawn
The stones and trees would greet him ﷺ
A cloud would shade him in heat and during travel
He would hear the glorification of the stones before prophethood and after it
