[16].Surah An-Nahl [The Bees] : Ayat 84-85

Ayat 84. And (remember) the Day when We shall raise up from each nation a witness (their Messenger), then, those who have disbelieved will not be given leave (to put forward excuses), nor will they be allowed (to return to the world) to repent and ask for Allah's Forgiveness (of their sins, etc.).

Ayat 85. And when those who did wrong (the disbelievers) will see the torment, then it will not be lightened unto them, nor will they be given respite.

Hazrat Abu Hurairah (May Allah be pleased with him) said: The Messenger of Allah [SAWW](PBUH)  said, "Allah, the Exalted, becomes angry, and His Anger is provoked when a person does what Allah has declared unlawful.''

[Al-Bukhari Book 07, Chapter 62, Hadith # 150].

Lesson : as mentioned above in Surah An-Nahl Ayat 85. "And when those who did wrong (the disbelievers) will see the torment" This Hadith warns us against committing sins and all that Allah has forbidden in order to avoid exciting the anger of Allah.
