There is nothing called as triple talaq in Islam. Talaq is 3 months waiting period as per Quran. Please see below verses related to talaq..
“Divorced women remain in waiting for three periods, and it is not lawful for them to conceal what Allah has created in their wombs if they believe in Allah and the Last Day. And their husbands have more right to take them back in this [period] if they want reconciliation. And due to the wives is similar to what is expected of them, according to what is reasonable. But the men have a degree over them [in responsibility and authority]. And Allah is Exalted in Might and Wise.(Quran 2:228)
Divorce is twice. Then, either keep [her] in an acceptable manner or release [her] with good treatment. And it is not lawful for you to take anything of what you have given them unless both fear that they will not be able to keep [within] the limits of Allah . But if you fear that they will not keep [within] the limits of Allah , then there is no blame upon either of them concerning that by which she ransoms herself. These are the limits of Allah , so do not transgress them. And whoever transgresses the limits of Allah – it is those who are the wrongdoers.”(Quran 2:229)
O Prophet (SAW)! When you divorce women, divorce them at their ‘Iddah (prescribed periods), and count (accurately) their ‘Iddah (periods). And fear Allah your Lord (O Muslims), and turn them not out of their (husband’s) homes, nor shall they (themselves) leave, except in case they are guilty of some open illegal sexual intercourse. And those are the set limits of Allah. And whosoever transgresses the set limits of Allah, then indeed he has wronged himself. You (the one who divorces his wife) know not, it may be that Allah will afterward bring some new thing to pass (i.e. to return her back to you if that was the first or second divorce). (Quran 65:1)
Then when they are about to fulfil their term appointed, either take them back in a good manner or part with them in a good manner. And take for witness two just persons from among you (Muslims). And establish the witness for Allah. That will be an admonition given to him who believes in Allah and the Last Day. And whosoever fears Allah and keeps his duty to Him, He will make a way for him to get out (from every difficulty). (Quran 65:2)
