As-Salaam alaykum,

Ayat 156 of Surat Baqra of the Holy Qur'an (2:156) reads:--

"We belong to Allah, and to Him we shall return."

With this, we realize that when we say: 'We belong to Him', we are declaring that nothing is deserved. Everything we have is a pure act of grace and blessing of/from Allah, Tabaraka Wa Ta'ala. Once this fact reaches our heart, we will be able to break free from arrogance, pride and complaint.
