Hadhrat Sa'd bin Abu Waqqas (Radhi Allahu Ta'ala 'Anhu) said that when this ayat came down, "Let us call our sons and your sons..." Holy Qur'an, (3:61) Allah's Holy Last Messenger (Sall Allahu alaihi wa Aalihi wa Sallim) called Sayyidina 'Ali, Sayyidah Fatima, Sayyidina Hasan and Sayyidina Husain (Radhi Allahu Ta'ala 'Anhum) and said, "O Allah, these are the members of my family." (Sahih Muslim)

Mother of faithful believers, Sayyidah 'A'isha (Radhi Allahu Ta'ala 'Anha) said that the Holy Nabi (Sall Allahu alaihi wa Aalihi wa Sallim) went out one morning wearing a striped cloak of black goat's hair. Sayyidina Al-Hasan bin 'Ali (Radhi Allahu Ta'ala 'Anhu) came and he took him under it, then Sayyidina al-Husain (Radhi Allahu Ta'ala 'Anhu) came and went under it along with him, then Fatima (may Allah be pleased with her) came and he took her under it, then 'Ali (Karam Allah Wajhu) came and he took him under it. He then recited (the following Ayat): "Allah only desires to remove abomination from you, members of the family, and purify you." Holy Qur'an, (33:33) (Sahih Muslim)


Hadhrat Zaid bin Arqam (Radhi Allahu Ta'ala 'Anhu) reported Allah's Messenger (Sall Allahu alaihi wa Aalihi wa Sallim) as saying, "I am leaving among you something of such a nature that if you lay hold of it you will not go astray after I am gone, one part of it being more important than the other: Allah's Book, a rope stretched from heaven to earth, and my close relatives who belong to my household. These two will not separate from one another till they come down to the Pond, so consider how you would act regarding them after my departure." (Sahih Tirmidhi)


Hadhrat Abu Dharr (Radhi Allahu Ta'ala 'Anhu) while holding the door of the Ka'ba, said that he had heard the Holy Nabi (Sall Allahu alaihi wa Aalihi wa Sallim) say, "My family among you are like Noah's ark. He who sails on it will be safe, but he who holds back from it will perish." (Musnad Ahmad bin Hambal)


Hadhrat Zaid bin Arqam (Radhi Allahu Ta'ala 'Anhu) said that Allah's Messenger (Sall Allahu alaihi wa Aalihi wa Sallim) said of Sayyidina Ali (Radhi Allahu Ta'ala 'Anhu), Sayyidah Fatima (Radhi Allahu Ta'ala 'Anha), Sayyidina al-Hasan (Radhi Allahu Ta'ala 'Anhu) and Sayyidina al-Husain (Radhi Allahu Ta'ala 'Anhu), "I am war to him who makes war on them and peace to him whom makes peace with them." (Tirmidhi)

HAZRAT ZAID BIN ARQAM (RAZE ALLAH O TALLAH) reported Prophet Muhammad(SAW)
i am leaving among u something of such a nature that if u lay hold of it u will never go astray after i am gone
,Allah's book n AHl e bait .someone asked who r Ahl e bait he replied
AAL E ALI,AAL E JAAFAR,AAL E AQEEL n AAL E ABBAS.
(PRECEPT NO 6321 SAHEE MUSLIM).
similarly in SURAH ALAHZAAB ALLAH says
O Prophet!sayto ur wives:if it be that u desire the life of this world n its glitter,then come !i will provide for ur enjoyment
n set u free in a handsome manner(28)
but if u seek Allah n His messenger n the home of hereafter ,verily Allah has prepared for the well doers amongst u a great reward(29).
O Wives of the prophet!if any of u were guilty of evident unseemly conduct ,the punishment would be doubled to her n that is easy for ALLAH(30)
but any of u that is devout in the service of Allah n His messenger ,n works righteousness,to her shall we grant her reward twice ,n we have prepared for her a generous sustenance(31)
O wives of the Prophet!u r not like any of the other women if u do fear Allah be not too complaisant of speech lest one in whose heart is a disease should be moved with desire but speak a speech that is just(32)
n saty quietly in ur houses n make not a dazzling display,like that of the former times of ignorance n establish regular prayer n give zakat n obey Allah n His mesenger.and Allah only wishes to remove all abomination from u,these r ur Ahl e Bait O Prophet n ALLAH want to make them pure n spotless(33).
these verses of Quran show that all the wives of Hazrat Muhammad were also included in Ahl e Bait.
