The lady who attempted to poison the Holy Prophet Muhammad (PBUH) was Hind bint Utbah, a prominent figure among the Quraysh tribe in pre-Islamic Mecca.
Hind was known for her fierce loyalty to her tribe and her hatred for the Prophet and his followers. She was driven by revenge after the Battle of Uhud, where her father, Utbah ibn Rabi'ah, and her uncle, Shaybah ibn Rabi'ah, were killed by Muslim forces.
Hind's act of poisoning was a deliberate attempt to harm the Prophet and undermine the nascent Muslim community. However, her plan failed, as the Prophet was miraculously saved by the grace of Allah.
The incident highlights the intense hostility and persecution faced by the early Muslims, who were subjected to various forms of oppression and violence by the Quraysh.
