Migration to Medina – Under the Cover of Night (The Promised Messiah’s (as) Narration)
According to the Promised Messiah (as), the Holy Prophet (sa) left his home in the morning. The Promised Messiah (as) states:
“None of the opponents saw the Holy Prophet (sa) when he left, even though it was morning and all of the opponents were stood surrounding the house of the Holy Prophet (sa). It was just as God Almighty stated in Surah Ya Sin that a covering was placed over the eyes of those unfortunate people and the Holy Prophet (sa) left them in a state that they were utter humiliated.”
(Surma Chashm-e-Arya, Ruhani Khazain, Vol. 2, p. 66 [footnote])
In any case, there are various narrations, but they all state that the disbelievers had no knowledge.
