What is the authenticity of the the Shiite narration: "Before the Qa'im there will be two deaths: a red death and a white death, until five out of every seven perish"?

The narrations of the Shia are not reliable because they do not adhere to the conditions for authenticating hadith (definition). The high death toll at the end of time has been established as one of the signs of the Hour, but there is no mention of this alleged Qaim. The signs of the Hour include two deaths that will afflict people like the disease affecting sheep, trials that will enter every house, and an abundance of harj (killing). There will also be land subsidence, transformations, and projectiles due to the prevalence of wickedness, and the number of believers and Arabs will decrease at the end of time due to trials and killing.
