Surah Yunus, Ayat 65-66

Ayat 65. And let not their speech grieve you (O Muhammad  [SAWW](PBUH), for all power and honour belong to Allah. He is the All-Hearer, the All-Knower.

Ayat

66. No doubt! Verily, to Allah belongs whosoever is in the heavens and whosoever is in the earth. And those who worship and invoke others besides Allah, in fact they follow not the (Allah's so-called) partners, they follow only a conjecture and they only invent lies.

Hazrat Sahl bin Saad As-Saaidi (May Allah be pleased with him) reported: Messenger of Allah  [SAWW](PBUH) said, "Were this world worth a wing of mosquito, He would not have given a drink of water to an infidel.''

[At-Tirmidhi Number 2320]. 

Lesson : as mentioned above in Surah Yunus Ayat 66. "No doubt! Verily, to Allah belongs whosoever is in the heavens and whosoever is in the earth". This Hadith makes it clear that the world and its wealth and riches has no significance to Allah. Thus, it should not have much significance to the believers. It should be considered a means to reform the Afterlife, or a place of trial.
