Upon this, the following verse was revealed:

اِنَّ شَانِئَکَ ہُوَ الۡاَبۡتَرُ ٪﴿۳﴾

Indeed, your enemy is an abtar (cut off from all good in the Hereafter) (Surah Kauthar v. 3)

The mubaarak name of Rasulullah (sallallahu ‘alaihi wasallam) is taken by millions of people (unlike his enemies).

One month after hijrah, an animal bit ‘Aas on his leg, causing it so swell to such an extent that it became as thick as a camel’s neck. This wound eventually led to his death.

Nubaih and Munabbih, the Sons of Hajjaaj

Nubaih and Munabbih were also bitter enemies of Rasulullah (sallallahu ‘alaihi wasallam). Whenever they laid eyes on Rasulullah (sallallahu ‘alaihi wasallam), they would say, “Could Allah not find anyone else to appoint as His messenger?”

Both of them were killed in the Battle of Badr.
