The Remembered and the Forgotten
Imām Ibn Taimiyyah, may Allāh have mercy on him, said:
The People of the Sunnah die, and mention of them [still] lives on [while] the People of Al-Bidʿah¹ die, and mention of them dies. [That’s] because the People of the Sunnah brought to life what the Messenger ﷺ came with, [by practicing it and calling to it], so for them is a portion of His saying:
وَرَفَعْنَا لَكَ ذِكْرَكَ
And I have raised high for you the mention of you [in this life and the Hereafter]. (Al-Sharḥ, 4)
The People of Al-Bidʿah, [meanwhile], hated what the Messenger ﷺ came with, so for them is a portion of His saying:
إِنَّ شَانِئَكَ هُوَ الْأَبْتَرُ
Indeed, the one who hates you [and that which] you have come with, he’s the one who is cut off [from being mentioned and remembered after his death]. (Al-Kawthar, 3)
So beware, beware, man, of hating anything of that which the Messenger ﷺ came with or rejecting it […].
