'Amir ibn Qays said:

Three Ayaat in the Book of Allah that I have sufficed myself with concerning my state of affairs, I read the saying of Allah the Majestic:

{And if Allah touches you with harm, there is none who can remove it but He; and if He intends any good for you, there is none who can repel His Favor [Al-An’aam: 17]

So I knew and was sure that if Allah wanted harm for me, no one upon the face of the Earth would ever be able to protect me from it, and if He wanted to give me something, no one would be able to take it away from me.

And I read his saying:

{Therefore remember Me (by praying, glorifying, etc.). I will remember you, and be grateful to Me (for My countless Favors on you) and never be ungrateful to Me. [Al-Baqarah: 152]

So I occupied myself with His remembrance and not others.

And I read his saying:

{And no (moving) living creature is there on earth but its provision is due from Allah. [Hood: 6]

So I knew, and was certain, and increased in confidence that my provision from Allah would not be taken by other than me.
