Answer
(Fatwa: 446/376/B=1431)
When he pronounced three talaqs, the three took place. In the age of the holy Prophet Muhammad (صلى الله عليه وسلم) ,a sahabi named Hadhrat Owaimir Ajlani (رضى الله تعالى عنه) gave his wife three talaqs in front of the holy Prophet Muhammad (صلى الله عليه وسلم). The holy Prophet Muhammad (صلى الله عليه وسلم) implemented all the three ones, the words of hadith are as follows:
فطلقها ثلاث تطليقات عند رسول الله صلى الله عليه وسلم ، فأنفذه رسول الله صلى الله عليه وسلم و كل ما صنع عند رسول الله صلي الله عليه وسلم سنت . (ابو داؤد ج:1/ص:307)
This hadith is sahih. After giving three talaqs it is not lawful to take wife back without halalah. The holy Quran says it clearly:
فَإِن طَلَّقَهَا فَلاَ تَحِلُّ لَهُ مِن بَعْدُ حَتَّىَ تَنكِحَ زَوْجاً غَيْرَهُ . [البقرة : 230]
Thereafter, if he divorces her, she shall no longer remain lawful for him unless she marries a man other than him.
