About thanks to Allah for His Mercy

Allah Almighty Says :
If you are grateful, then I will give you even more. And if you are ungrateful, then the torment from Me is heavy ”
Koran, (sura 14“ Ibrahim ”, ayah 7).

The Almighty said: “On that day you will be asked about pleasures” (Sura 102 “The Passion to Increase,” ayah 8).

Abu Hurayrah (may Allah be pleased with him) narrates the words of the Prophet (peace and blessings of Allaah be upon him):

“The Lord will meet his servant, and say to him:“ O such and such! Have I not honored you, exalted you, and bestowed upon you a spouse? Have I not subdued horses and camels to you? And haven’t I given you the opportunity to rule and enjoy life? ” He will answer: “Yes, it is.” Allah will say: “Did you think that you would meet Me?” He will answer: “No.” Then Allah will tell him: “Today I will forget you just as you have forgotten Me!”

Then He will meet another, and say to him: “Have I not honored you, exalted you and gave you a spouse? Have I not subdued horses and camels to you? And haven’t I given you the opportunity to rule and enjoy life? ” He will answer: “Yes, my Lord, it is all so.” Allah will say: “Did you think that you would meet Me?” He will answer: “No.” Then Allah will tell him: “I will forget you just as you have forgotten Me!”

Then He will meet the third slave and tell him the same. Then this person will say: “I believed in You, Your Book, Your Messenger, and I prayed, fasted and gave alms” – and he will start praising himself. Then Allah will say: “Then stay here.” And then he will be told: “Now are we going to send a witness against you?” He will think, “Who can be a witness against me?” Then Allah will seal his mouth and say to his thigh and his flesh and his bones: “Speak!” – and his thigh, and his flesh, and his bones, will speak, telling about all his deeds. This will be done to destroy his excuses. And this is the hypocrite, and he is the one on whom the wrath of the Most High will fall. ”
