It is narrated from Sayyiduna Mu'adh bin Jabal (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "Allah Almighty began this matter with prophethood and mercy; soon there will be caliphate and mercy; then there will be kingship of oppression and transgression; and then there will be tyranny, oppression and corruption. In the Ummah people will regard (unlawful) private parts as lawful, and will regard wine and silk as lawful; they will be helped in that and they will be given provision, until they meet Allah Almighty."
