Oman's Sultan Haitham bin Tariq issued a decree removing the name of his predecessor from the national anthem Thursday, a day after official mourning for Sultan Qaboos ended.

"Sultan Haitham issued a decree amending Annex 3 of the law pertaining to the state flag, emblem and national anthem," the official Oman News Agency reported.

According to the new decree, the lyrics referring to Sultan Qaboos, "Qaboos has come with the blessing of heaven, be cheerful and commend him to the protection of our prayers" will be replaced with "raise to the sky and fill the universe with light, be happy and prosper".

Sultan Qaboos, who died on January 10 at the age of 79, was the longest-serving leader in the modern Arab world. He left no apparent heir.
