فَوَلَجْتُ غَابَةَ الْجَمْعِ
So I entered the thicket of the crowd.
Walajtu means “I entered.” Ghābah denotes a forest or thickly wooded place, but the people are not literally trees. The phrase compares the density of the gathering to a forest.
This is more vivid than merely saying “I entered the meeting.” We feel him moving into a packed, noisy mass.
