Interior Cabinet Secretary Fred Matiang'i has declared Monday, July 11 a public holiday to mark Idd-ul-Adha.
According to Islamic teaching, Idd-ul-Adha (the feast of slaughtering) takes place on the 10th day of the third month after Ramadhan.
Idd-ul-Adha is an Islamic festival to commemorate the willingness of Abraham to follow Allah's command to sacrifice his son.
It also marks the end of Hajj, the annual Islamic pilgrimage to Mecca.
It is one of the two Idd celebrations, Idd-ul-Adha and Idd-ul-Fitr, and is often considered the holier of the two.
During the festival Muslims around the world gather to mark one of the holiest days in the religious calendar.
