عن عائشة رضي الله عنها قالت: استأذن رجل على رسول الله صلى الله عليه وسلم وأنا عنده فقال بئس ابن العشيرة أو أخو العشيرة ثم أذن له فلما دخل ألان له القول فلما خرج قلت يا رسول الله قلت ما قلت ثم ألنت له القول فقال: يا عائشة إن من شر الناس من تركه الناس أو ودعه الناس اتقاء فحشه (الشمائل المحمدية للترمذي، الرقم: 333)

Hazrat Aa’ishah (radhiyallahu ‘anha) reports:

On one occasion, while I was present with Rasulullah (sallallahu ‘alaihi wasallam), a certain person sought permission to enter his noble presence. (Before the person entered the mubaarak presence of Rasulullah (sallallahu ‘alaihi wasallam)), Rasulullah (sallallahu ‘alaihi wasallam) remarked, “How evil is this person from the people of his tribe”. Rasulullah (sallallahu ‘alaihi wasallam) then permitted him to enter. When he entered, Rasulullah (sallallahu ‘alaihi wasallam) spoke to him in a polite and courteous manner. After he left, I asked Rasulullah (sallallahu ‘alaihi wasallam), “O Rasul of Allah (sallallahu ‘alaihi wasallam)! You mentioned to me (prior to his entry) that which you mentioned (regarding his condition), yet you thereafter spoke to him in a polite and courteous manner?” Rasulullah (sallallahu ‘alaihi wasallam) then replied, “O Aa’ishah (radhiyallahu ‘anha)! Indeed the worst person is he whom people avoid or disassociate with in order to save themselves from his evil.”

Ubayy bin Khalaf followed in the footsteps of his brother, Umayyah bin Khalaf, in his hostility towards Rasulullah (sallallahu ‘alaihi wasallam).

On one occasion, he picked up a decomposed bone and brought it before Rasulullah (sallallahu ‘alaihi wasallam). He then crushed it in his hands, scattered its fragments into the wind and mockingly asked, “Will Allah be able to resurrect this?” Rasulullah (sallallahu ‘alaihi wasallam) replied, “Yes! Allah Ta‘ala will resurrect this bone as well as your bones after they decompose, and He will then hurl you into the fire of Jahannum.”

Umayyah would openly and publicly revile Rasulullah (sallallahu ‘alaihi wasallam). When he would pass by Rasulullah (sallallahu ‘alaihi wasallam), he would mockingly wink his eyes. Due to this behaviour of his, the following surah was revealed:

وَیۡلٌ لِّکُلِّ ہُمَزَۃٍ لُّمَزَۃِۣ ۙ﴿۱﴾ الَّذِیۡ جَمَعَ مَالًا وَّ عَدَّدَہٗ ۙ﴿۲﴾ یَحۡسَبُ اَنَّ مَالَہٗۤ اَخۡلَدَہٗ ۚ﴿۳﴾ کَلَّا لَیُنۡۢبَذَنَّ فِی الۡحُطَمَۃِ ۫﴿ۖ۴﴾ وَ مَاۤ اَدۡرٰىکَ مَا الۡحُطَمَۃُ ؕ﴿۵﴾ نَارُ اللّٰہِ الۡمُوۡقَدَۃُ ۙ﴿۶﴾ الَّتِیۡ تَطَّلِعُ عَلَی الۡاَفۡـِٕدَۃِ ؕ﴿۷﴾ اِنَّہَا عَلَیۡہِمۡ مُّؤۡصَدَۃٌ ۙ﴿۸﴾ فِیۡ عَمَدٍ مُّمَدَّدَۃٍ ٪﴿۹﴾

Woe unto every backbiter and person who taunts! He who accumulates wealth and repeatedly counts it. Does he think that his wealth will bring him eternity? Never! Verily, he will be hurled into the crushing fire! And do you know what is the crushing fire? It is the kindled fire of Allah Ta‘ala which will leap over the hearts. Indeed, the fire will be sealed over them in extended pillars. (Surah Humazah)

Umayyah bin Khalaf was slain in the Battle of Badr, wither at the hands of Hazrat Khubaib (radhiyallahu ‘anhu) or Hazrat Bilaal (radhiyallahu ‘anhu).

(Extracted from Deeratul Mustafa 1/214-215)

عن عائشة رضي الله عنها قالت: ما رأيت رسول الله صلى الله عليه وسلم منتصرا من مظلمة ظلمها قط ما لم ينتهك من محارم الله تعالى شيء فإذا انتهك من محارم الله تعالى شيء كان من أشدهم في ذلك غضبا وما خير بين أمرين إلا اختار أيسرهما ما لم يكن مأثما (الشمائل المحمدية للترمذي، الرقم: 332)

Hazrat Aa’ishah (radhiyallahu ‘anha) reports, “I never saw Rasulullah (sallallahu ‘alaihi wasallam) ever (become angry and) take revenge for his personal self in regard to any injustice that was done to him, (and he never expressed anger) so long as the limits of Allah Ta‘ala were not broken. However, if any of the limits of Allah Ta‘ala were violated, Rasulullah (sallallahu ‘alaihi wasallam) would become extremely angry on account of that. Whenever Rasulullah (sallallahu ‘alaihi wasallam) was given a choice between two options, he always chose the easier option, provided it (the option he chose) was not a sin.”
