Do you believe in personal revelation? If you prayed, would you get an answer?
Yes, I believe personal revelation... It can come in the form of a dream, a feeling, etc.
About prayers, they are always answered but it is a little bit more complicated (du'aa means prayer):
Whoever makes du’aa’ to his Lord receives an answer in all cases. The answer to prayers is not only getting what one asked for; rather there are two other responses that may come which are: warding off evil from the person who made du’aa’, commensurate with his du’aa’, and storing up the reward for the du’aa’ which the person will receive on the Day of Resurrection.
Allah has promised us, on the lips of His Messenger (peace and blessings of Allah be upon him), that whoever calls upon Him, fulfilling the conditions of du’aa’ will receive one of these responses.
It was narrated that Abu Sa’eed al-Khudri (may Allah be pleased with him) said: The Messenger of Allah (peace and blessings of Allah be upon him) said: “There is no Muslim who calls upon Allah with a du’aa’ in which there is no sin or severing of family ties, but He will give him one of three things: either He will answer his prayer, or he will store up an equal amount of good (reward) for him, or He will ward off an equal amount of evil from him.” They said, “O Messenger of Allah, then we shall say a lot of du’aa’?” He said, “Allah is most Generous.” Narrated by Ahmad, 10709.
All of this is what is meant by the verses:
“And your Lord said: ‘Invoke Me [i.e. believe in My Oneness (Islamic Monotheism) and ask Me for anything] I will respond to your (invocation). Verily, those who scorn My worship [i.e. do not invoke Me, and do not believe in My Oneness, (Islamic Monotheism)] they will surely enter Hell in humiliation!’” [Ghaafir 40:60]
“And when My slaves ask you (O Muhammad) concerning Me, then (answer them), I am indeed near (to them by My Knowledge). I respond to the invocations of the supplicant when he calls on Me (without any mediator or intercessor). So let them obey Me and believe in Me, so that they may be led aright” [al-Baqarah 2:186]
It may be better for the person not to get what he asked for his du’aa’, because of evil or fitnah (trial) that may result from his getting it, of which he is unaware. So Allah wards that off from him and gives him something that is better for him in this world, by warding off evil from him, or something that is better for him in the Hereafter, by storing up the reward of the du’aa’ for him.
