A--- 艾布·达伍德及其他人转述，赛义德·本·贾姆汗述自赛福奈（Safinah）的话："安拉的使者ﷺ说："

A--- Narrated Abu Dawud and others on the authority of Sa'id Ibn Jamhan after Safinah as saying: Allah's Messenger (Peace be upon him) says:

“先知之后的哈里发制度将持续三十年，之后真主将王权赐予祂所意欲的人。”（提尔米兹、艾布·达伍德、艾哈迈德和哈基姆辑录）

"The Caliphate after Prophethood will last for thirty years, then Allah grants kingship to whom He wills." (At-Tirmidhi, Abu Dawud, Ahmed and Al-Hakim)

这意味着这一时期包括阿布·伯克尔、欧麦尔、奥斯曼和阿里的统治时期，愿真主喜悦他们所有人。阿布·伯克尔在位两年零三个月，欧麦尔在位十年零六个月，奥斯曼在位十二年，阿里在位四年零九个月，而三十年的圆满则以为哈桑·伊本·阿里所进行的效忠宣誓（Bai'ah）来完成，即六个月。

This implies the period lasted by Abu Bakr, 'Umar, 'Uthman and `Ali, may Allah be pleased with them all. Abu Bakr stayed for two years and three months, 'Umar for ten years and six months, 'Uthman for twelve years, `Ali for four years and nine months, and in completion of the thirty years comes the Bai'ah (Pledge of allegiance) given for Al-Hasan Ibn 'Ali, that is six months.

第一位穆斯林君主是穆阿维叶(愿安拉喜悦他),他是他们之中最优秀的。此后出现了严酷而不公正的统治,直到欧麦尔·本·阿卜杜勒·阿齐兹出现。事实上,逊尼派穆斯林学者视他为第五位哈里发,因为他完全遵循了前四位哈里发的道路。

The first Muslim king was Mu'awiyah (May Allah be pleased with him) who was the best among them all. Then, followed a severe and unjust kingship, up till the time when `Umar Ibn 'Abdel'Aziz came. Indeed, the Sunni Muslim scholars regarded him as the fifth Caliph as he followed their (the previous four ones) very steps.
