When the prayer was granted Indirect

First: Supplication is worship and a form of obedience to God. The Prophet sallallaahu 'alaihi wa sallam said,
الدعاء هو العبادة
"Supplication is worship." (Narrated by Abu Dawud no. 1479, At-Tirmidhi no. 2969, Ibn Majah no. 3828 and Ahmad 4 / 267; of An Nu'man ibn Basyir)
Second: Supplication is the cause to prevent reinforcements' disaster.
Third: Benediction was very helpful with the permission of Allah. Benefits of prayer is in three circumstances as mentioned in the following hadith,
«ما من مسلم يدعو بدعوة ليس فيها إثم ولا قطيعة رحم إلا أعطاه الله بها إحدى ثلاث إما أن تعجل له دعوته وإما أن يدخرها له فى الآخرة وإما أن يصرف عنه من السوء مثلها». قالوا إذا نكثر. قال «الله أكثر»
"It is not a Muslim to say a prayer to God for sin and decided not contain Hospitality (among relatives, pen), but God will give him three things: [1] Allah will soon grant do'anya, [2] God will keep him at Hereafter, and [3] God will keep him that such ugliness. "The friend then said," Then we will multiply the prayer. "Prophet sallallaahu 'alaihi wa sallam then said," God will grant the prayers that reproduce -do 'a you. "(Narrated by Ahmad 3 / 18, from Abu Sa'id. Syu'aib Sheikh Al Arnauth said that isnaad jayyid)
Fourth: Benediction is because more and get stronger and help face the enemy.
Fifth: Benediction is a testament and recognition of one's true faith in God either in rububiyah, uluhiyah and His name and nature. Prayer of a man to his Lord indicated that he believed God exists and God is All-Ghoni (Supreme Sufficient), All-Seeing, Supreme Majesty, Most Gracious, Most Capable, Rabb diibadahi simply not entitled to any other.
Sixth: Benediction show proof of one's true resignation to God Almighty. Because a man pray when praying, he is asking for help in God. He also handed over his business to God means not merely on besides Him.
Seventh: Benediction of God's wrath is as a silencer. The Prophet sallallaahu 'alaihi wa sallam said,
من لم يسأل الله يغضب عليه
"Whoever does not ask to God, then God would be furious at him." (Narrated by Tirmidhi no. 3373. Sheikh Al Albani said that the hadeeth is hasan)
Hopefully, this knowledge gives us the benefits of motivation to continue to pray and a lot of pleading to God. Every prayer must be useful. Any prayers would be best given by God according to His. So do not break to continue begging.
Hopefully, a brief presentation at tonight useful.
