[Machine] This verse was revealed to the Messenger of Allah ﷺ while he was in the house of Umm Salamah. "Verily, Allah wants to remove impurity from you, O People of the Household, and purify you with a thorough purification." So, he called Hasan, Husayn, and Fatimah and sat them in front of him. He called Ali and sat him behind his back. Then he covered himself and them with a cloak. Then he said, "O Allah, these are the members of my household. Remove impurity from them and purify them with a thorough purification." Umm Salamah asked, "Can I be with them, O Messenger of Allah?" He replied, "You are in a good place."
نَزَلَتْ هَذِهِ الْآيَةُ عَلَى رَسُولِ اللهِ ﷺ وَهُوَ فِي بَيْتِ أُمِّ سَلَمَةَ {إِنَّمَا يُرِيدُ اللهُ لِيُذْهِبَ عَنْكُمُ الرِّجْسَ أَهْلَ الْبَيْتِ وَيُطَهِّرَكُمْ تَطْهِيرًا} فَدَعَا الْحَسَنَ وَالْحُسَيْنَ وَفَاطِمَةَ فَأَجْلَسَهُمْ بَيْنَ يَدَيْهِ وَدَعَا عَلِيًّا فَأَجْلَسَهُ خَلْفَ ظَهْرِهِ وَتَجَلَّلَ هُوَ وَهُمْ بِالْكِسَاءِ ثُمَّ قَالَ «اللهُمَّ هَؤُلَاءِ أَهْلُ بَيْتِي فَأَذْهِبْ عَنْهُمُ الرِّجْسَ وَطَهِّرْهُمْ تَطْهِيرًا» فَقَالَتْ أُمُّ سَلَمَةَ وَأَنَا مَعَهُمْ يَا رَسُولَ اللهِ؟ فَقَالَ «وَأَنْتِ مَكَانَكِ وَأَنْتِ عَلَى خَيْرٍ»
