The true possessor of all the blessings which a person witnesses in the life of this world is Allah. However, there are some who may fall into error by believing that they are the real owners of the blessings which Allah has granted them. With these blessings in their possession, they may forget their powerlessness in the sight of our Lord, and become arrogant though Allah has the power to take back everything He has given them whenever He wills. Because of this, it is necessary for all to recognize that every blessing is the gift of Allah, and to thank our Lord for our enjoyment of them. In order for people to understand this matter, Allah gives the following example in the Qur'an:
Make an example for them of two men. To one of them We gave two gardens of grape-vines and surrounded them with datepalms, putting between them some cultivated land. Both gardens yielded their crops and did not suffer any loss, and We made a river flow right through the middle of them. He was a man of wealth and property and he said to his companion, debating with him,
"I have more wealth than you and more people under me." He entered his garden and wronged himself by saying, "I do not think that this will ever end. I do not think the Hour will ever come. But if I should be sent back to my Lord, I will definitely get something better in return."
Of the two people referred to here in the Qur'an, the one who was more powerful in terms of wealth forgot that it was Allah Who gave him his property and riches, falsely believing that they were his own and becoming boastful. He believed that the gardens, which yielded their crops because Allah made them fertile, would never be destroyed or suffer any damage at all. In one way, it could be thought that his well protected orchard, through which a river passed and which had every promise of fertility, was of a beauty and magnificence which could never be harmed. But, it must be remembered that all things are subservient to Allah. Like everything in the universe, this garden was under Allah's control; every seed would grow only with Allah's permission, every branch sprouted because Allah ordered it. The river watered the roots of the date palms because Allah willed it. The garden remained thriving and fruitful on Allah's instruction; all could be destroyed just by Allah pronouncing "Be." In the Qur'an we are told that the man, who had forgotten that the provider of the blessings he possessed was Allah, was reminded that he should praise and exalt Allah's power and glory, on entering his orchard, and say, "It is as Allah wills [masha’llah], there is no strength but in Allah":
His companion, with whom he was debating, said to him, "Do you then disbelieve in Him Who created you from dust, then from a drop of sperm, and then formed you as a man? He is, however, Allah, my Lord, and I will not associate anyone with my Lord. Why, when you entered your garden, did you not say, 'It is as Allah wills, there is no strength but in Allah?' Though you see me with less wealth and children than you possess, it may well be that my Lord will give me something better than your garden and send down on it a fireball from the sky so that morning finds it a shifting heap of dust, or morning finds its water drained into the earth so that you cannot get at it." The fruits of his labor were completely destroyed and he woke up wringing his hands in grief, rueing everything that he had spent on it. It was a ruin with all its trellises fallen in. He said, "Oh, if only I had not associated anyone with my Lord!" There was no group to come to his aid, besides Allah, and he was not given any help. In that situation the only protection is from Allah, the Real. He gives the best reward and the best outcome. (Surat al-Kahf: 37-44)
As can be understood from these verses, by bringing about a natural disaster, Allah destroyed both the garden and the crops of this man, who was so proud of what was in his possession, to remind him that there is no other power than His. The owner of the garden, who had had everything he possessed destroyed, finally understood that he had no friend or helper other than Allah, and took refuge in Allah saying, "if only I had not associated anyone with my Lord!"
One of the lessons which needs to be drawn from this story provided in the Qur'an is that people should never at any time believe that their possessions are their own, and that they should speak in such a way as to exalt the glory of Allah, as saying, "It is as Allah wills, there is no strength but in Allah."
