There will be a rise in drug-related deaths and killings before the coming of Hazrat Mahdi (as)
Ali (as) says: "THERE WILL BE RED DEATH AND WHITE DEATH BEFORE THE COMING OF HAZRAT MAHDI...”
(Iqdud Durar, p. 98, Ghaybat Nomani, p. 397, Al-Ghayba li Sheikh al-Tusi, p. 267, Bihar al-Anwar, Vol. 52, p. 211)
This hadith note that killings will intensify in society prior to the coming of Hazrat Mahdi (as). As can clearly be seen from the hadith, WHITE DEATH will take place as described THROUGH WHITE POISON (all kinds of narcotics), and will kill people both physically and spiritually. The reference to RED DEATH (the color of blood) indicates that bloody murders will be committed in the time of Hazrat Mahdi (as). This rise in the number of RED AND WHITE DEATHS is one of the portents of the coming of Hazrat Mahdi (as).
