Allah - there is no deity except Him. And upon Allah let the believers rely.
Tafsir of "Ibn Kathir" (English)
Allah! La ilaha illa Huwa. And in Allah therefore let the believers put their trust.So, He first informs about Tawhid and its meaning. The implied meaning is to single Him out for deification, being purely devoted to Him, and relying upon Him, as He said;رَّبُّ الْمَشْرِقِ وَالْمَغْرِبِ لَا إِلَـهَ إِلاَّ هُوَ فَاتَّخِذْهُ وَكِيلًThe Lord of the east and the west; La ilaha illa Huwa. So take Him alone as Trustee. (73:9
