Allah says: Then on that Day you shall be asked about the delights!
Meaning: on that Day (of Judgement) you all will be questioned concerning your gratitude towards the favors that Allah blessed you with, such as health, safety, sustenance and other things.
You will be asked did you return His favors by being thankful to Him and worshipping Him.
It has been confirmed in Sahih Al-Bukhari and the Sunans of At-Tirmidhi, An-Nasa’i and Ibn Majah from Ibn `Abbas that the Messenger of Allah said:
“Two favors are treated unjustly by most people:
1) health and
2) free time. ”
This means that the people are lacking gratitude for these two favors.
Imam Ahmad recorded from Abu Hurayrah that the Prophet said:
“Allah the Mighty and Majestic says on the Day of Judgement:
“O Son of Adam! I made you ride upon the horses and camels, I gave you women to marry, and I made you reside and rule (in the earth). So where is the thanks for that?”
Ahmad was alone in recording this Hadith in this manner.
