Mu'tazila according to frustration and takfir

Frustration, the destruction of good deeds due to minor sins in the word of Mu'tazila; If it is unfaithful, it means good deeds erase small sins. According to the principle of Promise and Warning, the Mu'tazila argued that believers would go to heaven in the hereafter, while the two sinned believers were treated in these two conceptual centers. According to them, it is not in question to enter heaven with amnesty and bounty. Those who have great sin will enter into heaven with repentance, while the little sinners will be treated according to the multiplicity of their sins or sins. Sins of the very sin of the sin are deleted, the sins of the believer of the believer are destroyed too. Thus, in the Hereafter, the individual determines his fate. This thesis deals with the theory that the Mu'tazila defended by the concepts of frustration and takfir. In addition to this, it also sheds light on the evidence on the subject of Ahl-i Sunnah. Although frustration and takfir is an important opinion on the faithful life of the believers, they have been criticized for overriding the verses that have revealed the forgiveness of Allah in the Hereafter. Issues such as forgiveness, intercession, repentance are discussed in this thesis and the opinion of the Ahl al-Sunnah based on divine justice and compassion is based on the opinion of Mu'tazila and the unbelievers.
