It is narrated from Sayyidah Umm Habibah (may Allah be pleased with her) that the Messenger of Allah (peace and blessings be upon him) said: "The calamities and tribulations that my Ummah will be afflicted with have been shown to me; they will kill one another." In fact, this is something that has already been decreed by Allah Almighty, just as it happened in the previous nations. I asked Allah Almighty to grant me the opportunity to intercede on behalf of them (my followers), and Allah Almighty accepted my supplication."
