The benefits of the saying of Allah the Exalted: (( ... and whoever Allah leaves astray, for him there is no guide )) .

Among the benefits of this verse is that it is obligatory for a person, when he wishes to seek guidance, not to seek it from anyone other than Allah, in Whose hand are both misguidance and guidance. So do not seek guidance from anyone other than Allah (Mighty and Majestic); seek it from Allah (Mighty and Majestic).
It is also derived from it the entrusting of matters to Allah (Blessed and Exalted is He).
