Sa'eed bin Jumhan narrated: "Safinah narrated to me, he said: “The Messenger of Allah(s.a.w) said: "Al-Khilafah will be in my Ummah for thirty years, then there will be monarchy after that."' Then Safinah said to me: “Count the Khilafah of Abu Bakr,' then he said: “Count the Khilafah of 'Umar and the Khilafah of 'Uthman.' Then he said to me: “Count the Khilafah of 'Ali."' He said: "So we found that they add up to thirty years." Sa'eed said: "I said to him: “Banu Umaiyyah claim that the Khilafah is among them.' He said: “Banu Az-Zarqa' lie, rather they are a monarchy, among the worst of monarchies””””””"
