Allah says:

[إِنَّمَا يُرِيدُ اللَّهُ لِيُذْهِبَ عَنكُـمُ الرِّجْسَ أَهْلَ الْبَيْتِ وَيُطَهِّرَكُمْ تَطْهِيــراً]

(Allah wishes only to remove Ar-Rijs from you, O members of the family, and to purify you with a thorough purification.) This is a clear statement that the wives of the Prophet are included among the members of his family (Ahl Al-Bayt) here, because they are the reason why this Ayah was revealed, and the scholars are unanimously agreed that they were the reason for revelation in this case, whether this was the only reason for revelation or there was also another reason, which is the correct view. Ibn Jarir recorded that `Ikrimah used to call out in the marketplace:

[إِنَّمَا يُرِيدُ اللَّهُ لِيُذْهِبَ عَنكُـمُ الرِّجْسَ أَهْلَ الْبَيْتِ وَيُطَهِّرَكُمْ تَطْهِيــراً]

(Allah wishes only to remove Ar-Rijs from you, O members of the family, and to purify you with a thorough purification.) "This was revealed solely concerning the wives of the Prophet.'' Ibn Abi Hatim recorded that Ibn `Abbas said concerning the Ayah:

[إِنَّمَا يُرِيدُ اللَّهُ لِيُذْهِبَ عَنكُـمُ الرِّجْسَ أَهْلَ الْبَيْتِ]

(Allah wishes only to remove Ar-Rijs from you, O members of the family,) "It was revealed solely concerning the wives of the Prophet .'' `Ikrimah said: "Whoever disagrees with me that it was revealed solely concerning the wives of the Prophet , I am prepared to meet with him and pray and invoke the curse of Allah upon those who are lying.'' So they alone were the reason for revelation, but others may be included by way of generalization. Ibn Jarir narrated that Safiyyah bint Shaybah said: "`A'ishah, may Allah be pleased with her, said, `The Prophet went out one morning wearing a striped cloak of black camel's hair. Al-Hasan, may Allah be pleased with him, came and he wrapped him in the cloak with him. Then Al-Husayn, may Allah be pleased with him, came and he wrapped him in the cloak with him. Then Fatimah, may Allah be pleased with her, came and he wrapped her in the cloak with him. Then `Ali, may Allah be pleased with him, came and he wrapped him in the cloak with him, then he said:

[إِنَّمَا يُرِيدُ اللَّهُ لِيُذْهِبَ عَنكُـمُ الرِّجْسَ أَهْلَ الْبَيْتِ وَيُطَهِّرَكُمْ تَطْهِيــراً]

(Allah wishes only to remove Ar-Rijs from you, O members of the family, and to purify you with a thorough purification.) This was recorded by Muslim. In his Sahih, Muslim recorded that Yazid bin Hayyan said: "Husayn bin Sabrah, `Umar bin Muslim and I went to Zayd bin Arqam, may Allah be pleased with him, and when we had sat down with him, Husayn said: `You are so fortunate, O Zayd! You saw the Messenger of Allah and heard his speeches, and you went on military campaigns with him, and you prayed behind him. You are so fortunate, O Zayd! Tell us what you heard from the Messenger of Allah .' He said, `O son of my brother, by Allah, I have grown old and it has been a long time, and I have forgotten some of the things that I used to know from the Messenger of Allah . Whatever I tell you, accept it, and whatever I do not tell you, do not worry about it.' Then he said, `One day, the Messenger of Allah stood up to address us by the well of Khumm, between Makkah and Al-Madinah, and he praised Allah and thanked Him, and he preached and reminded us. Then he said:

«أَمَّا بَعْدُ، أَلَا أَيُّهَا النَّاسُ فَإِنَّمَا أَنَا بَشَرٌ يُوشِكُ أَنْ يَأْتِيَنِي رَسُولُ رَبِّي فَأُجِيبَ، وَأَنَا تَارِكٌ فِيكُمْ ثَقَلَيْنِ: أَوَّلُهُمَا كِتَابُ اللهِ تَعَالَى، فِيهِ الْهُدَى وَالنُّورُ فَخُذُوا بِكِتَابِ اللهِ وَاسْتَمْسِكُوا بِه»

(Thereafter! O people, I am merely a human being and soon the messenger of my Lord will come and I will answer him. I am leaving behind two things with you, the first of which is the Book of Allah in which is guidance and light, so seize the Book of Allah and hold fast to it.) He urged them to cling to the Book of Allah, then he said:

«وَأَهْلُ بَيْتِي أُذَكِّرُكُمُ اللهَ فِي أَهْلِ بَيْتِي، أُذَكِّرُكُمُ اللهَ فِي أَهْلِ بَيْتِي»

(And the members of my family (Ahl Al-Bayt): Remember Allah with regard to the members of my family, remember Allah with regard to the members of my family.) saying it three times.' Husayn said to him, `Who are the members of his family (Ahl Al-Bayt), O Zayd Are not his wives members of his family' He said, `His wives are members of his family, but the members of his family are those who are not permitted to receive charity after he died.' He said, `Who are they' He said, `They are the family of `Ali, the family of `Aqil, the family of Ja`far and the family of `Abbas, may Allah be pleased with them.' He said, `Were all of these forbidden to receive charity after his death' He said, `Yes.''' This Commentary is from Zayd bin Arqam and is not Marfu`
