The Khilafah is the general leadership over all the Muslims, in the whole world, whose responsibility is to implement the laws of Islam, and to convey the Islamic Message to the whole world. It is also known as the Imamah, so Imamah and Khilafah are synonymous. It is the shape that the Ahkam Shari’ah (divine laws) determine as the Islamic state. Many sahih Ahadith have been narrated using these two words, with the same meaning. None of these two words differed in their meaning from the other in any Shari’ah text i.e. the Qur’an and Sunnah, for they are the only divine texts. However, it is not binding to adhere to either of them, rather it is the meaning that has to be adhered to.

Appointing a Khaleefah is obligatory upon all Muslims throughout the world. Executing such a duty, just like executing any other duty which Allah (swt) has decreed on Muslims is compulsory, in which no choice or complacency is allowed. Failure in performing this duty is one of the gravest sins, which is deserving of Allah’s (swt) severe punishishment.

The evidence concerning the obligation of appointing a Khaleefah over all the Muslims is understood from the Sunnah and the Ijmaa’ of the Sahabah. As for the Sunnah, it has been narrated that Nafi’ said: ‘Umar told me: I heard the Messenger of Allah (pbuh) say:

“Whoever takes off his hand from an obedience to Allah, he will meet Him on the Resurrection Day without having any proof for himself; and whoever dies while there were no Bay’ah on his neck, his death would be that of the days of Jahiliyyah (ignorance).” [Narrated by Muslim] So the Messenger (pbuh) made it obligatory upon every Muslim to have a Bay’ah on his neck. He described the one who dies without having a Bay’ah on his neck as if he died the death of Jahiliyyah. The Bay’ah would not be valid except for the Khaleefah. The Messenger of Allah (pbuh) made it an obligation that every Muslim should have a Bay’ah on his neck for a Khaleefah, but he did not oblige every Muslim to give a Bay’ah to the Khaleefah. The obligation therefore, is the existence of a Bay’ah on the neck of every Muslim. This necessitates the existence of a Khaleefah, who, through his existence, is entitled to a Bay’ah (on the neck of every Muslim.) Thus, the existence of the Khaleefah is the issue that necessitates a Bay’ah on the neck of every Muslim, whether he actually gave the Bay’ah or not. Therefore, the Hadith is evidence that the appointment of a Khaleefah is obligation and that every Muslim is obliged to have Bay’ah on his neck; it is not an evidence suggesting that giving the Bay’ah is an obligation. This is because the Messenger of Allah (pbuh) rebuked the absence of the Bay’ah of allegiance on the neck of the Muslim till he dies, and not the abstention from giving the Bay’ah itself. Muslim narrated from Al-Araj from Abu Hurayrah from the Prophet (pbuh) that he (pbuh) said:
