Charged with murder, appellant was found guilty of voluntary manslaughter. On appeal he contends the evidence was insufficient to support the verdict; evidence of appellant’s prior criminal acts fatally tainted the judgment; and instructions to the jury were incomplete.
1. Construed in a light most favorable to the jury’s verdict, the evidence showed that appellant was engaged in a fight with the victim’s brother over whether or not the brother had a gun owned by appellant’s wife. Appellant and the victim’s brother were exchanging blows when the victim intervened. Although the victim, hearing and speech-impaired, used sign language to say he did not wish to fight, appellant turned his fury on the victim, who used a stool to fend off appellant’s blows. During this encounter appellant produced a knife with which he stabbed the victim in the heart, causing his death. Appellant then wiped the blade clean and left the scene. At trial, he claimed he acted in self-defense.
“A person commits the offense of voluntary manslaughter when he causes the death of another human being under circumstances which would otherwise be murder and if he acts solely as the result of a sudden, violent, and irresistible passion resulting from serious provocation sufficient to excite such passion in a reasonable person. . . .” OCGA § 16-5-2 (a). “The ‘sudden, violent, and irresistible passion’ contemplated by the statute ordinarily refers to anger or rage so intense ‘as to exclude all idea of deliberation or malice.’ [Cit.]” Murff v. State, 251 Ga. 478, 480 (306 SE2d 267) (1983). A heated argument suffices as sudden, violent irresistible passion. See Asbury v. State, 175 Ga. App. 335 (1) (333 SE2d 194) (1985); Brady v. State, 159 Ga. App. 389 (1) (283 SE2d 617) (1981); Green v. State, 152 Ga. App. 387 (1) (262 SE2d 639) (1979). The jury determined appellant acted without malice but also without justification. Inasmuch as there was evidence to support the jury’s conclusion that appellant was guilty of voluntary manslaughter beyond a reasonable doubt, we will not dis*4turb the judgment on the general grounds. Jackson v. Virginia, 443 U. S. 307 (99 SC 2781, 61 LE2d 560) (1979); Green, supra.
2. On rebuttal, over appellant’s objection, the State presented evidence of appellant’s involvement in a stabbing incident which occurred seven years before the act for which appellant was on trial. The State introduced the evidence of the earlier incident as a “similar act” to rebut appellant’s claim he was acting in self-defense when he fatally stabbed the victim. Immediately preceding the admission of the rebuttal testimony, the trial court informed the attorneys that testimony concerning the earlier stabbing would be allowed, but all reference to a burglary charge related to the stabbing was to be avoided. The rebuttal witness, the victim of the earlier stabbing, in response to the State’s query, “Did you do anything to him to cause him to stab you?,” stated, “No more than to stop him from burglarizing in my van.” In response to appellant’s immediate motion for a mistrial, the trial court instructed the jury to disregard everything except the fact that appellant had “cut” the witness in 1977. Appellant’s renewed motion for mistrial was denied. On appeal, appellant contends the dissimilarity between the two stabbing incidents as well as the seven-year lapse of time between them should have barred the admission of the evidence of the earlier stabbing. He also contends the rebuttal witness’ reference to the 1977 burglary was sufficient cause to grant a mistrial.
The transcript reveals that this witness’ testimony was admitted for the limited purpose to show bent of mind, motive, and scheme, and that the court refused to allow any reference to a prior burglary. The witness’ answer was unresponsive to the question and, upon motion, the trial court took prompt curative action by instructing the jury to “disregard anything with reference to anything except the fact that this man was cut by this defendant at a previous time in 1977, as the district attorney has just pointed out. Otherwise, you will pay no attention whatsoever and disabuse your minds of anything that this defendant [sic] might have said about any other offense involved in this situation.” The renewed motion for a mistrial was overruled and the court again instructed the jury to “disregard anything about this man, except that he was cut, as stated by the district attorney.”
It is not error for a trial court to refuse to grant a mistrial on account of the voluntary answer of a witness when corrective measures are applied immediately. Haynes v. State, 80 Ga. App. 99 (55 SE2d 646) (1949). When testimony placed in evidence is illegal, it is not an abuse of the trial court’s discretion to refuse to grant a mistrial if the court gives sufficient corrective instructions to rule out the testimony. This rule obtains even if the defendant’s character is placed in issue and especially applies where the testimony is volunteered by a witness and not directly elicited by the prosecutor. Jones v. State, *5167 Ga. App. 847, 848 (307 SE2d 735) (1983); Cross v. State, 136 Ga. App. 400 (221 SE2d 615) (1975).
With regard to the similar crimes issue, there is no requirement that a previous offense be absolutely identical to the one being prosecuted so as to make it admissible, Millwood v. State, 164 Ga. App. 699 (1) (296 SE2d 239) (1982), nor does the lapse of time between the two stabbings automatically require the exclusion of such evidence. Campbell v. State, 234 Ga. 130, 132 (214 SE2d 656) (1975). The trial court did not err on these two points. Even assuming there was error as to a nonconstitutional matter where, as here, the evidence was overwhelming, it is highly probable that the error did not contribute to the judgment. Therefore, the error, if any, is harmless. Johnson v. State, 238 Ga. 59, 61 (230 SE2d 869) (1976).
3. Appellant claims error in the trial court’s failure to give his requested instruction on lawful act/unlawful manner involuntary manslaughter. OCGA § 16-5-3 (b). While in the past “[fjrom time to time a defendant contend [ed] that self-defense [was] a ‘lawful act’ while the use of excessive force converted] that act into one performed in an ‘unlawful manner,’ thus justifying a charge based on [OCGA § 16-5-3 (b)]” (Crawford v. State, 245 Ga. 89 (3) (263 SE2d 131) (1980)), the flood of appeals raising such a contention was cut to a mere trickle by the Supreme Court’s opinion in Saylors v. State, 251 Ga. 735 (3) (309 SE2d 796) (1983). There, the court reached the inevitable conclusion that “a defendant who seeks to justify homicide under the ‘self-defense’ statute ... is not entitled to an additional instruction on involuntary manslaughter in the course of a lawful act . . . whatever the implement of death . . . For if he is justified in killing [in self-defense], he is guilty of no crime at all. If he is not so justified, the homicide does not fall within the ‘lawful act’ predicate of OCGA § 16-5-3 (b) . . ., for the jury, in rejecting his claim of justification, has of necessity determined thereby that the act is not lawful.” See also Wilson v. State, 176 Ga. App. 322 (335 SE2d 888) (1985); Thomas v. State, 174 Ga. App. 560 (2) (330 SE2d 777) (1985).
4. Appellant correctly notes that the trial court never informed the jury they should acquit appellant if they found appellant to have acted in self-defense, his sole defense. “Where there is only one defense on which a party relies, to fail to instruct the jury as to this defense so specifically that the jury will be not only required to pass upon it, but will be able to do so intelligently under pertinent rules of law and evidence, virtually withdraws that defense. ...” Smith v. State, 147 Ga. App. 549 (3) (249 SE2d 353) (1978). See Dinnan v. State, 173 Ga. App. 191 (1) (325 SE2d 851) (1984). In this case the trial court thoroughly instructed the jury on self-defense, and there was no legal requirement to explain to the jurors that if they accepted the defendant’s defense they should acquit. Lavender v. State, 234 *6Ga. 608, 609 (216 SE2d 855) (1955).
5. Appellant also takes issue with the charges on reasonable doubt, mutual combat, and the burden of proof with regard to the defense of self-defense. Our review of the charge as a whole finds the instructions complained of to be sufficient. See Payne v. State, 233 Ga. 294 (V) (210 SE2d 775) (1974).
Judgment affirmed.
