One of the name of God is "Assamad"

This expression means: Allah is He on Whom all depend. All creatures need Him for their sustenance and are certain they will get what they ask Him for.

 People ask God for their needs both here and Hereafter and they know that they will receive from Him what they need proportionate with their strength.
