KHAYR – خَيْر
Etymology & Literal Meaning: Literally means good, better, best, beneficial, or meritorious. Etymologically, it derives from the root kh-y-r ( خ ي ر ) — the same root from which the word ikhtiyâr (choice or free will) is derived — signifying the selection and preference of what is finest and most excellent, thereby expressing that the ultimate and absolute good is what Allah wills, chooses and decrees. This haqiqah lying in the deep meaning of this word is perfectly expressed in the saying:
الْخَيْرُ فِيمَا اخْتَارَهُ اللَّهُ1
reflecting that what Allah wills, chooses and creates is the absolute khayr.
As an Islamic Term: It expresses any form of righteous deed, thought and virtue informed and guided by the Sharî‘ah. It encompasses ‘amal as-sâlih filled with nûr, as well as essential ni‘mahs like the intellect, ‘ilm, ‘ibâdah, justice, beneficence, taqwâ, tawakkul, shukr, patience, worldly property and health — or even an event that appears outwardly as a calamity — that serve as a means of gaining the pleasure and acceptance of Allah, thereby becoming the source of eternal happiness in the âkhirah. It is the absolute opposite of sharr.
Moreover, it is one of the beautiful names and attributes of Allah, al-Khayr, as the absolute source and fountainhead of all goodness.

1 “The khayr is precisely in what Allah has chosen and decreed.” While not a literal âyah or a hadîth, the expression الْخَيْرُ فِيمَا اخْتَارَهُ اللَّهُ (El-khayru fî mâkhtarahullâh) is a saying widely embraced in Islamic scholarly and Sufi traditions. Often attributed to personages, such as Hazrat ‘Ali (ra) or other Islamic authorities, it reflects the Qur'anic principle highlighted in Surah al-Baqarah (2:216): "And it may be that you dislike a thing which is khayr for you and that you like a thing which is sharr for you. Allah knows, while you do not know." (Tr.)
