Why does Islam call to all mankind?

Islam calls people to embrace it because it is the final religion that abrogated the previous religions, and Allah will not accept any other religion, as He states: "And whoever seeks a religion other than Islam, it will never be accepted of him, and in the Hereafter he will be among the losers." Islam is the most merciful, easiest, and most suitable of religions for all times and places. Therefore, everyone must embrace it, act upon it, and call others to it.
