Prohibition of doing that which Allah and His Messenger have Prohibited

Imam Al-Nawawi’s Riyad-us-Saliheen
Chapter 368
Prohibition of doing that which Allah and His Messenger have Prohibited

Allah, the Exalted, says:

And let those who oppose the Messenger’s commandment (i.e., his Sunnah legal ways, orders, acts of worship, statements) (among the sects) beware, lest some Fitnah (disbelief, trials, afflictions, earthquakes, killing, overpowered by a tyrant) should befall them or a painful torment be inflicted on them.” (24:63)

And Allah warns you against Himself (His punishment).” (3:30)

Verily, (O Muhammad (sallallaahu ’alayhi wa sallam)) the Grip (punishment) of your Rubb is severe.” (85:12)

Such is the Seizure of your Rubb when He seizes the (population of) towns while they are doing wrong. Verily, His Seizure is painful and severe.” (11:102)

1806. Abu Hurairah (May Allah be pleased with him) said: The Prophet (sallallaahu ’alayhi wa sallam) said, “Allah, the Exalted, becomes angry, and His Anger is provoked when a person does what Allah has declared unlawful.”
