Ayat al-Tathir · the Verse of Purification
آيَة التَّطْهِير
إِنَّمَا يُرِيدُ اللَّهُ لِيُذْهِبَ عَنكُمُ الرِّجْسَ أَهْلَ الْبَيْتِ وَيُطَهِّرَكُمْ تَطْهِيرًا
Allah only wishes to remove all impurity from you, O People of the House, and to purify you with a thorough purification.
Allah testifies to the purity of the Ahlulbayt (ع). The grammar shifts in the middle of the verse — singling them out — and the Prophet ﷺ gathered Ali, Fatima, Hasan, and Husayn (peace be upon them) under his cloak when this was revealed.
