Fine Qualities
`A'isha told that the Prophet went out one morning wearing a striped[1] cloak of black goat's hair. Al-Hasan b. `Ali came and he took him under it, then al-Husain came and went under it along with him, then Fatima came and he took her under it, then `Ali came and he took him under it. He then said, "God only desires to remove abomination from you, members of the family, and purify you[2]." It literally means one decorated with representations of camels' saddles. Quran, 33:33. Muslim transmitted it.
وَعَنْ عَائِشَةَ قَالَتْ: خَرَجَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ غَدَاةً وَعَلَيْهِ مِرْطٌ مُرَحَّلٌ مِنْ شَعْرٍ أَسْوَدَ فَجَاءَ الْحَسَنُ بْنُ عَلِيٍّ فَأَدْخَلَهُ ثُمَّ جَاءَ الْحُسَيْنُ فَدَخَلَ مَعَهُ ثُمَّ جَاءَتْ فَاطِمَةُ فَأَدْخَلَهَا ثُمَّ جَاءَ عَلَيٌّ فَأَدْخَلَهُ ثُمَّ قَالَ: [إِنَّمَا يُرِيدُ اللَّهُ لِيُذْهِبَ عَنْكُمُ الرِّجْسَ أهل الْبَيْت وَيُطَهِّركُمْ تَطْهِيرا] رَوَاهُ مُسلم
