Allah encourages His servants to call upon Him, and He guarantees to respond. Qatadah said that Ka’b Al-Ahbar said, ”This Ummah has been given three things which were not given to any nation before, only to Prophets.
• When Allah sent a Prophet, He said to him, 
`You are a witness over your nation.’ But 
you have been made witnesses over 
• it was said to the Prophets individually, 
`Allah has not laid upon you any hardship 
in religion,’ but He said to this entire 
Ummah (and 
(Allah) has not laid upon you in religion 
any hardship), (22:78) and 
• it was said to the Prophets individually; 
`Call upon Me, I will answer you,’ but it 
was said to this Ummah, 
(Call upon Me, I will answer you).” 
This was recorded by Ibn Abi Hatim. 
Imam Ahmad recorded that Al-Nu`man bin Bashir, may Allah be pleased with him, said, 
“The Messenger of Allah said: Indeed the supplication is the worship.” 
Then he recitedَ, And your Lord said: “Call upon Me, I will 
answer you. Verily, those who scorn My 
worship they will surely enter Hell in 
This was also recorded by the Sunan compilers; 
At-Tirmdhi, An-Nasa’i, Ibn Majah, and Ibn Abi Hatim and Ibn Jarir.
