[19].Surah Maryam [Mary] : Ayat 77-80

Ayat 77. Have you seen him who disbelieved in Our Ayat (this Qur'an and Muhammad  [SAWW](PBUH) and (yet) says: "I shall certainly be given wealth and children [if I will be alive (again)],"

Ayat 78. Has he known the unseen or has he taken a covenant from the Most Beneficent (Allah)?

Ayat 79. Nay! We shall record what he says, and We shall increase his torment (in the Hell);

Ayat 80. And We shall inherit from him (at his death) all that he talks of (i.e. wealth and children which We have bestowed upon him in this world), and he shall come to Us alone.

[Tafseer] Besides the man who boasts of wealth and power in actual possession, there is a type of man who boasts of getting them in the future and builds his worldly hopes thereon. Is he sure? He denies Allah, and His goodness and Mercy. But all good is in the hands of Allah. Can such a man then bind Allah to bless him when he rejects faith in Allah? Or does he pretend that he has penetrated the mysteries of the future? For no man can tell what the future holds for him. Has he penetrated to the Unseen, or has he taken a contract with ((Allah)) Most Gracious? Nay! We shall record what he says, and We shall add and add to his punishment. Such a man deserves double punishment-for rejecting Allah, and for his  blasphemies with His Holy Name. To Us shall return all that he talks of and he shall appear before Us bare and alone. Literally, "We shall inherit", Cf. 19:40. Even if the man had property and power, it must go back to the source of all things, and the man must appear before the Judgment Seat, alone and unaccompanied, stripped of all the things from which he expected so much! 

Hazrat Abu Hurairah (May Allah be pleased with him) reported: The Messenger of Allah [SAWW](PBUH) said, "On the Resurrection Day, the rights will be paid to those to whom they are due so much so that a hornless sheep will be retaliated for by punishing the horned sheep which broke its horns". 

[Muslim Book 032,Chapter 13, Hadith # 6252] 

Lesson : as mentioned above in Surah Maryam Ayat 80."We shall inherit from him (at his death) all that he talks" This Hadith makes it abundantly clear that there will be utmost justice on the Day of Resurrection. So much so that Allah will redress even the grievance of the aggressed animals against the aggressors. Thus, this Hadith serves a severe warning for people. When animals, who are devoid of sense, will not be forgiven, how would mankind be, which is gifted with senses? The latter will not be pardoned if they are guilty of having been unjust to anyone without adequately compensating them.
