ثُمَّ يَرْمِي الَّتِي تَلِيهَا مِثْلَ ذَلِكَ وَيَقِفُ عِنْدَهَا
Translation: Then he stones the one next to it in the same way and stands by it.
This is the middle Jamarah. The phrase mithla dhālik refers back to the first station's procedure: seven separate pebbles with takbir, followed by standing.
The earlier manner also includes supplication, so the same supplication pattern is followed after the second Jamarah. The first two stations resemble each other in this respect.
