The reliance on Allah (AWJ) is associated with Al-'Ibaadah

Thus, all what Allah (SWT) has ordered His 'Ibaad as to the causes is an aspect of 'Ibaadah. And the reliance is associated with A l-'Ibaadah as in the saying of Allah (SWT),

So worship Him (O Muhammad SAAWS) and put your trust in Him. [Hood:123]; and His (SWT) saying,

Say: 'He (Allah) is my Lord! None has the right to be worshiped but He! On Him is my trust, and to Him will be my return and repentance.' [Ar Ra'd:30]; and the saying of Shou'aib,

In Him (Allah) I trust and unto Him I repent. [Hood:88]

Amongst these people, too, is a group who leave the favored of the deeds but not the duties. Thus they are desparaged accordingly.
