Did the Messenger, may Allah bless him and grant him peace, pray at the grave of Musa, upon him be peace?

The Prophet, peace and blessings be upon him, did not pray at the grave of Moses or any other prophets. Rather, he prayed two rak'ahs with the prophets in Jerusalem on the night of Al-Isra wal-Mi'raj. The narrations that report his prayer in Medina, or at the grave of Moses, or Al-Khalil (Abraham) are fabricated and موضوعة (forged).
