[16].Surah An-Nahl [The Bees] : Ayat 78

Ayat 78. And Allah has brought you out from the wombs of your mothers while you know nothing. And He gave you hearing, sight, and hearts that you might give thanks (to Allah). 

Hazrat Abu Dharr (May Allah be pleased with him) said: The Messenger of Allah  [SAWW](PBUH) said, "O My slaves, were the first of you and the last of you, the human of you and jinn of you to be as pious as the most pious heart of any man of you, that would not increase My domain a thing. O My slaves, were the first of you, and the last of you, the human of you and the jinn of you to be as wicked as the most wicked heart of any man of you, that would not decrease My domain in a thing. O My slaves, were the first of you and the last of you, the human of you and the jinn of you to stand in one place and make a request of Me, and were I to give everyone what he requested, that would not decrease what I have, any more than a needle decrease the sea if put into it. O My slaves, it is but your deeds that I reckon for you and then recompense you for, so let him who finds good (i.e., in the Hereafter) praise Allah and let him who finds other than that blame no one but himself.''' [Muslim Chapter 32, Hadith # 6246]. 

Lesson : as mentioned above in Surah An-Nahl Ayat 78. This Hadith mentions the Power and Majesty of Allah and stresses that one should supplicate Allah for everything that one needs. From guidance to sustenance, the treasures of everything are with Him - the treasures which are unlimited and any withdrawal from them does not make any reduction in them. Similar is the case of His Sovereignty; it is not affected even if the whole universe supports or opposes them. Thus, it is in the interest of man that he should dedicate himself entirely to Allah and beg all his needs from Him and Him Alone.
