*Women impure are for men impure, and men impure for women impure and women of purity are for men of purity, and men of purity are for women of purity: **these are not affected by what people say: for them there is forgiveness, and a provision honourable. ***Quran: 24:26
Prophet (saw) followed the commands of the Quran to the full.
As the above ayah clearly states that men of purity must marry women of purity.
And Prophet (saw) being the purest of the pure did marry only pure women and Hz. Ayeisha (ra) is one of them and is not effected by what people say.
Now will our Shia brothers and sisters here say that Prophet (saw) ignored the above of the Quranand married a vile scheming lady??? Purety means in body and soul.
No human apart from the Prophets ( peace be upon them all) are infallible.
Hz. Ayeisha (ra) by her own admission did err and did repent for it.
Desipte what people say about her she will be Prophet's (saw) wife in Jannah.
