From Sahih Bukhari (Hadith 7450):
Narrated Anas:The Prophet (ﷺ) said, "Some people will be scorched by Hell (Fire) as a punishment for sins they have committed, and then Allah will admit them into Paradise by the grant of His Mercy. These people will be called, 'Al-Jahannamiyyin' (the people of Hell)
