Al-Quran is a reference book of Islamic propagation. The Qur'an has its own way of conveying propaganda to man. There are several methods of da'wah submitted by the Qur'an, among them with methods of promise and threats. The terms promises and threats have been discussed by experts among the Mu'tazila with the concept of wa'ad and wa'id. In the book of al-Milal wa al-Nihal by AsySyahrastani mentions what is meant by wa'ad and wa'id according to ahlussunnah including the original Kalam Allah. Allah promises rewards for those who carry out His commands and threaten with torment for everyone who transgresses. Everyone who carries out his command is entitled to reward according to the promise of goodness and every wretched person has the right to be tortured for doing a prohibited act. It has nothing to do with reason. Meanwhile the Mu'tazila argue that wa'ad and wa'id are not = Allah's kalam at the time of the Azaan but the command and the prohibition, the promise of reward and the threat of punishment based on the new kalam. Whoever survives because he executes the command and gets the reward. Whoever loses because he violates the threat. As a result he got the punishment and all that was obtained through reason. Many examples of verses about promises and threats are spreading in the Qur'an. The expression of promises and threats in the Qur'an has distinctive features and editorials. Each of the verse's editors has the following characteristics: the verse editorial of the promise is usually characterized by: First, expressed by the sentence of condition, with the custom of the word man and the answer with the word fa. Secondly, the editorial of the appointment is also expressed with the sentence ististna (exceptions). Thirdly, the wording of the promise is expressed in the word wabasysyiri. Meanwhile, the verse about the threat usually has the following characteristics: First, expressed in the word wail. There are 27 times the word wail in the Qur'an. Second, expressed by the terms of condition. Third, expressed by the phrase wabasysyiri (convey the good news). Da'wah method through promise gives a very big influence to people who believe in Allah SWT. that is, first, the method of promise can motivate the believers to worship sincerely and multiply doing good. Second, people of faith and righteous deeds are more patient in facing the tough trials of life in the world.

Among these, first, people who believe in Allah SWT. and faith in the Day of Resurrection will be afraid of death and life after death. Therefore, he will be motivated to worship sincerely and multiply righteous deeds.
