It is narrated from Sayyidah Asma' bint Abi Bakr (may Allah be pleased with her); she said: When the surah "Perish the hands of Abu Lahab" [Surah al-Masad: 1] was revealed, Umm Jamil bint Harb (the wife of Abu Lahab, who was one-eyed) came shrieking and wailing, with a stone in her hand, saying these (insolent verses): "Mudhammaman abayna, wa dinahu qalayna, wa amrahu 'asayna" (We rejected Mudhammam, that is Muhammad, we abandoned his religion, and we disobeyed his command). The Prophet (peace and blessings be upon him) was sitting in the mosque, and with him was Sayyiduna Abu Bakr (may Allah be pleased with him). When Sayyiduna Abu Bakr (may Allah be pleased with him) saw her, he said: "O Messenger of Allah! She has come, and I fear that she will see you." The Messenger of Allah (peace and blessings be upon him) said: "She will never see me." He (peace and blessings be upon him) recited some verses of the Qur'an, and he was kept safe from her (coming under Allah's protection) just as he had said; and he recited this verse: "And when you recite the Qur'an, We place between you and those who do not believe in the Hereafter a concealed barrier." [Surah al-Isra': 45] She came and stood by Sayyiduna Abu Bakr (may Allah be pleased with him), but she did not see the Messenger of Allah (peace and blessings be upon him). She said: "O Abu Bakr! I have been told that your companion has satirised me." Sayyiduna Abu Bakr (may Allah be pleased with him) said: "By the Lord of this House (the Ka'bah), he has not satirised you at all." The narrator said: So she turned back, saying: "Quraysh know that I am the daughter of their chief." The chain of this hadith is sahih (authentic), and the two Shaykhs did not record it.
