Ibn Malak wrote on ijmâ’ in his book Usûl al-fiqh: “If the mujtahids of a certain era did not agree on how an action should be done and explained it differently, the scholars succeding them should follow the words of one of them and it is not permissible for them to offer an explanation that would not agree with any of those different explanations. This principle was established with an ijmâ’, i.e. with the consensus of all scholars.” There is not a mujtahid in any part of the world today. ‘Mujtahid’ means ‘an Islamic scholar who has attained to the grade of ijtihâd’. Not from ourselves do we say that there is no mujtahid on the earth today; all scholars have been declaring this, including Hadrat Shâh
Walî-Allah ad-Dahlawî, whose name Mawdûdî tries to exploit as a false witness. For example, Ibn ’Âbidîn, while commenting on the statement, “Muadhdhin’s crying very loud will spoil their salât,” in ad-Durr al-mukhtâr, wrote: “Throughout the four hundred years following Rasûlullah’s (’alaihi ’s-salâm) death there has been no great scholar to do qiyâs, nor any mutlaq mujtahid to derive rules by comparing one affair to another.” As declared in the Hadîth, profound scholars who would attain to the grade of ijtihâd would come every hundred years, but these people would be mujtahids within a madhhab, who would not undertake the task of doing qiyâs, that is, performing new ijtihâd, but they would try to restore the ijtihâd of the leader of the madhhab to which they belonged and to lead people to the right course, since there would be no need for new ijtihâd and their sole task would be to reinforce the teachings of the scholars of Ahl as-Sunna. A Muslim who is not a mujtahid is called a muqallid (follower). Today, we
all the Muslims on the earth are muqallids. No matter how much learned a muqallid is, he cannot do ijtihâd over a matter disagreeing with what the mujtahids have communicated before; this is understood from the unanimity quoted from Ibn Malak above. The hadîth, “My umma will not agree on deviation,” indicates that this unanimity of scholars is a means of salvation and is correct.
