It is a condition for the empowering of a delegated assistant (Tafwid), that his empowerment encompasses two issues: The first being general responsibility, and the second being the representation. Accordingly, it is necessary for the Khalifah to say to him “I appoint you on my behalf as my deputy” or anything that is of a similar meaning from the wordings that encompass the general responsibility and representation. This authorisation enables the Khalifah to send the assistants to specific locations, or transfer them to other places and other work as is required as the assistant of the Khalifah, and without the need for a new authorisation since it all falls under the original empowerment.

The evidence for this is the reality of the work of the assistant, since the minister of Tafwid, or the assistant of Tafwid, who is the minister that the Khalifah appointed to carry the responsibility of ruling and authority with him. He is authorised to manage the affairs according to his opinion, and to conduct them according to his Ijtihad in agreement with the Shari’ah rules, and so the Khalifah empowers him with a general handling and representation. The representation here is a contract, and contracts are not correct unless they are contracted with a direct word, and so for this reason, it has been made a condition that empowering an assistant must occur with wording that indicates he is a representative in the place of the Khalifah and has the general control. Such as if the Khalifah said to him “I granted you what is upon me, to act on my behalf”, or says, “I made you a minister, and decided upon your representation” or something similar. In other words, it should encompass the general representation and general control by any manner it is understood, so it is imperative that the empowerment of the assistant is upon words that indicate the reality of the assistant, which is the representative of the Khalifah, and takes everything in terms of mandatory powers which the Khalifah has. In other words, it is imperative that the contract of ministry with the assistant is upon a wording which encompasses two conditions: the first being general control, the second being representation, and if the wording does not explicitly cover these two conditions, then the ministry for the assistant is not contracted.
