The wife of Abu Lahab, Ummu Jameel bintu Harb, the sister of Hazrat Abu Sufyaan bin Harb (radhiyallahu ‘anhu), also harboured intense enmity and hostility for Rasulullah (sallallahu ‘alaihi wasallam). During the night, she would scatter thorns on the path of Rasulullah (sallallahu ‘alaihi wasallam).
When Ummu Jameel learnt that a surah of the Qur’aan Majeed was revealed regarding her and her husband, she picked up a stone and rushed to strike Rasulullah (sallallahu ‘alaihi wasallam). At that moment, Rasulullah (sallallahu ‘alaihi wasallam) was with Hazrat Abu Bakr (radhiyallahu ‘anhu) in Musjid-ul-Haraam.
When Ummu Jameel arrived in the musjid, Allah Ta‘ala placed a veil over her sight due to which only Hazrat Abu Bakr (radhiyallahu ‘anhu) was visible, and she was unable to see Rasulullah (sallallahu ‘alaihi wasallam). Ummu Jameel asked Hazrat Abu Bakr (radhiyallahu ‘anhu), “Where is your companion? I heard that he ridicules me and makes mocking remarks regarding me! By Allah! If I find him now, I will strike him with this stone! By Allah! I am an expert poetess!”
Saying this, she recited the following poetry:
مُذَمَّمًا عَصَيْنَا وَأَمْرَهُ أَبَيْنَا وَدِيْنَهُ قَلَيْنَا
Muzammam we defied, his instructions we rejected and his religion we despised
Due to her enmity and hatred, she would refer to Rasulullah (sallallahu ‘alaihi wasallam) as ‘muzammam’ instead of Muhammed. Muzammam is the actually antonym of Muhammed. Muhammed means “the praised one”, while Muzammam means “the one who is despised”.
After speaking these words, Ummu Jameel departed.
