It is narrated from Hazrat Umm Salamah (may Allah be pleased with her) that when she learned of the martyrdom of Hazrat Imam Hussain, she cursed the people of Iraq, saying: "They martyred Hussain, may Allah's curse be upon them. They deceived and distressed Hussain, may Allah's curse be upon them. I have seen the time when once the Prophet (peace and blessings be upon him) was in her house, and Hazrat Fatimah came with a pot in which there was Khazirah (a type of food). The Prophet (peace and blessings be upon him) said to her, 'Call your husband and children as well.' So Hazrat Ali and the two Hasans (Hasan and Hussain) also came and sat down to eat the Khazirah. The Prophet (peace and blessings be upon him) was at that time in a state of sleep on a platform, with a cloak from Khyber under his blessed body, and I was praying in the room. During this, Allah revealed this verse: 'O People of the House, Allah only wishes to remove impurity from you and to purify you thoroughly.' After that, the Prophet (peace and blessings be upon him) took the remaining part of the cloak and covered all of them with it, and he extended his hand outside and pointed towards the sky and said, 'O Allah, these are my Ahl al-Bayt and my special ones, so remove impurity from them and purify them thoroughly.' He prayed this twice. Upon this, I put my head into the room and said, 'O Messenger of Allah, am I not among your family?' The Prophet (peace and blessings be upon him) said, 'Why not? You also come under the cloak.' So after the Prophet's (peace and blessings be upon him) supplication, I also entered under it."
