Shia ayatolla Jafar as-Subhani in his Rasail wal Maqalat p 139, wrote:

وقال: اللهم إن لكل نبي أهل بيت وهؤلاء أهل بيتي. ولما أرادت أم سلمة
أن تدخل تحت الكساء منعها وقال: أنت على خير ولست من أهل البيت.

And (prophet, sallahu alaihi wa ala alihi wa sallam) said: “O My Allah! Each messenger had his ahlalbayt, and these are my ahlalbayt”. And when Umm Salamah wanted to enter under the cloak, he prevented her and said: YOU ARE UPON GOODNESS AND NOT FROM AHLALBAYT.

We have discussed hadith of Cloak and verse of purification in details in previous articles (1,2).

And now I’d like to challenge all shias to present a single hadith, where prophet (sallalahu alaihi wa ala alihi wa sallam) would say to Umm Salamah: YOU ARE UPON GOODNESS AND NOT FROM AHLALBAYT.
