Allah Ta’ala said (translation): And your Lord says, “Call upon Me; I will respond to you.” Indeed, those who disdain My worship will enter Hell [rendered] contemptible. [Quran, 40:60]
And when My servants ask you concerning Me – indeed I am near. I respond to the invocation of the supplicant when he calls upon Me. So let them respond to Me [by obedience] and believe in Me that they may be [rightly] guided. [Quran, 2:186]
The Prophet sallallahu alaihi wa sallam said, Supplication (du’a’) is itself the worship. (He then recited:) “And your Lord said: Call on Me, I will answer you.” [Abi Dawud 1479]
Your Rabb (Lord of the Universe) is Modest and Generous, and would never turn the hands of a slave without gain when he raises them to Him (in supplication). [Related by the four lmams except An-Nasa’i.]
He also said,
Whenever a Muslim supplicates Allah, He accepts his supplication or averts any similar kind of trouble from him until he prays for something sinful or something that may break the ties of kinship.” Upon this someone of the Companions said: “Then we shall supplicate plenty.” The Messenger of Allah (ﷺ) said, “Allah is more plentiful (in responding). [At- Tirmidhi]
