the benefit of supplication 

   

 The supplication is the worship because when the servant supplicates Allah, he then acknowledges His Lordship and Divinity, and since the servant knows that there is no God but Allah, he will acknowledge His Oneness, will put his trust upon Him in all of his affairs, and will seek refuge from every evil in Him alone. On the contrary, whoever denies the Oneness of Allah, and denies His Ability to do whatever He wills, he will turn away from supplicating Allah out of His arrogance ans stubbornness, so the supplication is the worship, and Allah has threatens whoever turns away from His worship with Hellfire on the day of resurrection as He has stated in Aya (60) of Surat Ghafir "And Your Lord said, call upon Me, I will respond to you, indeed, those who are arrogant to worship Me will enter Hellfire, humiliated", and as narrated by Alnu'man Bin bashir that the Prophet Muhammad (PBUH) said: "The supplication is the worship then He recited: "And Your Lord said, call upon Me, I will respond to you, indeed, those who are too arrogant to worship Me will enter Hellfire, humiliated" (Jami' Altirmidhi 2969).

 Thereupon, Allah promises His servants that He will respond to their supplication, but Allah has set conditions for the supplication to be answered, including that the servant responds to Allah and submits to Him with obedience and submission, where Allah addresses His Messenger Muhammad (PBUH) in Aya (186) of Surat Albaqarah saying "And when My servants ask You concerning Me, indeed, I am near, I respond to the supplication of the supplicant when he calls upon Me, so Let them respond to Me and believe in Me that they may be rightly guided", or that He does not supplicate for sin or severing of ties of kinship, or that he does not hasten the answer and does not abandon the supplication, where as narrated by Abu Hurayrah that the Messenger of Allah (PBUH) said: "The supplication of the servant is granted in case he does not supplicate for sin or for severing the ties of kinship, or he does not become impatient, it was said Allah's Messenger! What does he does not become impatient imply?, He said that he should say I supplicated and I supplicated but I did not find it being answered, and thus he becomes frustrated and abandons supplication" (Sahih Muslim 2735).

 Allah commanded His servants to call upon Him humbly and secretly in Aya (55) of Surat Ala'raf, so He commanded them to single Him out of worship, to call upon Him in submission and humility of their hearts, and not to raise their voices in supplication out of hypocrisy, and Allah  assures that He does not love the aggressors and the tyrants who transgress the limits of Allah in supplication or anything else, and as narrated by Abu Musa Alash'ari: "We were along with the Prophet (PBUH) on a journey, and the people began to pronounce Allahu Akbar: Allah is the Most Great, loudly, so the Prophet said O people! Show mercy to yourselves for you are not calling one who is deaf nor is He absent, indeed, you are calling One who is All-Hearing, Ever-Near, and is with you" (Sahih Muslim 2704 a).
