“Said one person who had knowledge of the Book: I will bring it to you within the twinkling of any eye.” (27:40)

The person who said this was Asif-e-Barqiya, the Prime Minister of King Sulaiman (as). According to this statement, he said, he can bring the throne of Bilqees in less than a second. Quran confirms;

“Then when Sulaiman saw the (throne was) placed before him.”

As he said, the throne of Bilqis was there, just in front of Hazrat Sulaiman (as), which he brought in less than a second.
Now, what was the reaction of Hazrat Sulaiman(as) when he saw this incredible achievement of his Prime Minister ?
Did he say any word in praise of his Prime Minister, who did the job and brought the throne from a far distance in just less than a second ? NO.
Not at all. Quran tells that immediately after seeing the throne there,

“He (Sulaiman) said: This is by the grace of my Lord., to test me whether I am grateful or ungrateful.” (27:40)

Hazrat Sulaiman considered the incredible achievement of his Prime Minister, a great favor of Allah and accordingly thanked Him and praised Him and not the man who apparently did it. Then he further generalized all human achievements as the favors of Allah and said:

“And if anyone is grateful, truly his gratitude is (a gain) for his own soul, but if any is ungrateful, truly, My Lord is free of all needs, Supreme in Honor”. (27:40)
Thus, the important lesson which we can get from this true story of Quran is that, we should not be impressed by the person who performs any great achievement or we should not feel proud if we do any great service. In all cases, we should glorify Allah and we should thank Allah, as He is the One Who deserves for that. It is because, He is the creator of man, and He is the One Who provides the opportunity to someone to do any incredible thing.
So, He is the One who should be glorified and thanked for His favor. Those who do not realize this fact are the most ignorant, thankless and cheap people. Most of the scientists and great people of the world who are known for their great achievements are among these cheap people.
Similarly, many ignorant people worship great people because they do not realize the Divine Power behind these great people.
History reveals that whenever, the Chief Commander of the faithful, Hazrat Ali, killed any strong kafir in the battle field, he always said Allah-o-Akbar. i.e. clearly acknowledging the Divine Power, glorifying His Might, and thanking His great favor.

Second Condition - Allah alone is the prime source of all blessings

a - Complete trust in God

We must believe that the ultimate result of everything is in Allah’s hands only.

Quran reflects:
“And to Allah go back all questions for decision.” (22:76)

• NO pilot can say for sure that he will reach to his destination safely.
  
  Yuri Gagarin, a highly experienced Soviet air force pilot and the first cosmonaut who circled the earth at the height of 327 kilometers in space (in April 12, 1961) at a speed of 27000 kph, died in a plane crash.
  Hundreds of airplane which take off at every minute land safely to their destination only by the Grace of All-Mighty Allah.
