عَنْ عَلِيِّ بْنِ زَيْدٍ عَنْ أَنَسِ بْنِ مَالِكٍ أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ كَانَ يَمُرُّ بِبَيْتِ فَاطِمَةَ سِتَّةَ أَشْهُرٍ إِذَا خَرَجَ إِلَى الْفَجْرِ فَيَقُولُ ”الصَّلَاةَ يَا أَهْلَ الْبَيْتِ {إِنَّمَا يُرِيدُ اللَّهُ لِيُذْهِبَ عَنْكُمُ الرِّجْسَ أَهْلَ الْبَيْتِ وَيُطَهِّرَكُمْ تَطْهِيرًا} [الأحزاب: 33]“
It is narrated from Sayyiduna Anas bin Malik (may Allah be pleased with him) that for six months, it was the practice of the Noble Prophet (peace and blessings be upon him) that when he would pass by the house of Sayyidah Fatimah (may Allah be pleased with her) at the time of Fajr prayer, he would say: O people of the household! Perform the prayer. Verily, Allah only intends to remove all impurity from you (the people of the household) and to purify you completely.
