Sabily is a free and open source operating system based on the Ubuntu Linux distribution. One main feature that distinguishes Sabily from other Ubuntu Linux distribution is that Sabily was designed by Muslims for Muslims. The Sabily open source operating system offers Islamic software such as Islamic prayer time applications (minbar, firefox-praytimes), a Qur'an study tool (zekr) and a Web content filtering utility (webstrict) and an Islamic calendar (hijra).
In May, 2011, the Sabily team released Sabily 11.04, codename Al-Badr. Sabily was formerly Ubuntu Muslim Edition.
