Every living has its own sustenance. The amount will not get accidentally exchanged even a bit. Allah himself who meets any of His creatures that live on this earth, the following are some of the ways of Allah in giving sustenance to all His creatures according to Al Quran:
1. The first level of sustenance is guaranteed by Allah
” And there is not a beast in the earth but the sustenance thereof dependeth on Allah.” (QS. Hud: 6).
This means that God will give you health, food, drink for his entire creature on earth. It is the lowest basic sustenance.
2. The second level of sustenance obtained in accordance with what is sought.
“And that man hath only that for which he maketh effort.” (QS. An-Najm: 39).
Allah will provide sustenance in accordance with what he did. If someone works for two hours, it can be the result of the two hours. If you work longer, more diligent, more knowledgeable, more seriously, someone will get more. No point of view he was a Muslim or infidel.
3. The third level of sustenance is more sustenance for the people who are grateful.
“And when your Lord proclaimed: If ye give thanks, I will give you more; but if ye are thankless, lo! My punishment is dire “ (Qur’an, Ibrahim: 7)
This is the sustenance for people who are loved by Allah. People who are grateful are able to feel the love of God and are fortunate to get more.
That is the promise of Allah. The people who are grateful will live happy, prosperous and peaceful. His business will be very successful, because Allah always adds their sustenance.
4. The fourth level of sustenance is a special sustenance any way that is unexpected for those who fear and put their trust in Allah.
“…..Whose believeth in Allah and the Last Day is exhorted to act thus. And whosoever keepeth his duty to Allah, Allah will appoint a way out for him, And will provide for him from (a quarter) whence he hath no expectation. And whosoever putteth his trust in Allah, He will suffice him. Lo! Allah bringeth His command to pass. Allah hath set a measure for all things.
The fourth provision is special sustenance, not everyone can reach it. This provision will be given from any way that is unexpected. Perhaps when a person is desperately need.
