Jazakallahu khayran (جَزَاكَ اللَّهُ خَيْرًا) means “may Allah reward you with good”. It is the Islamic way to say thank you. The usual replies are wa iyyākum (“and you too”) or wa antum fa-jazākumullāhu khayran.
What Jazakallah Khair means
Instead of thanking someone with words only, you ask Allah to repay them, because Allah’s reward is better than anything you can give. The Prophet ﷺ said this is the fullest way of praising someone who has done you a favour.
The ending changes with the person you are thanking: -ka for a man, -ki for a woman, -kum for a group (also used for one person as a mark of respect).

Where it comes from
In the Qur’an
هَلْ جَزَآءُ ٱلْإِحْسَٰنِ إِلَّا ٱلْإِحْسَٰنُ
Is the reward for good [anything] but good?
In the hadith
“Whoever has a favour done for him and says to the one who did it, jazākallāhu khayran, has done the utmost in praising him.”
Jami at-Tirmidhi 2035
Common mistakes
- Dropping “khayran”. Jazāk Allāh alone means “may Allah repay you”, which can be good or bad. Adding khayran (with good) makes the dua clear.
- Using the wrong ending. Jazāka for a man, jazāki for a woman, jazākum for a group.
- Thinking there is one required reply. No reply wording is fixed in the sunnah. Returning the dua is simply good manners.
