The verse of Purification (Ayat al-Tathir) verse is given its name due to the mentioning of purity in the last line. According to Umm Salama, the verse of purification was revealed in her home when only Muhammad, Ali, Fatima, Hasan, and Husayn were present. Scholars such as Tarbasi and Tha'labi have described Umm Salama narrating: "One day Lady Fatima having cooked some food brought it to my house for the Prophet. The Prophet said, 'O the light of my eyes, call Ali and your sons so that we may eat this food together.'" When all had gathered and they had eaten from that food, Angel Jibra'eel descended and revealed the following verse: "Indeed God desires to repel all impurity from you, O People of the Household, and purify you with a thorough purification."
