(Zumar) 39 : 11
قُلْ إِنِّي أُمِرْتُ أَنْ أَعْبُدَ اللَّهَ مُخْلِصًا لَهُ الدِّينَ
You say: Indeed I am commanded to serve The Lord sincerely submitting all life to Him.
Through this verse, Messengers and believers are commanded to declare individually that they are living here as vicegerents of the Lord, serving Him alone. See explanation 1: 4; 39: 2-3.
