Anyway, are you sure this time that Al Qurba includes all the relatives of the Prophet (saww)? my 2nd question is, who do you think includes Aal e Ibrahim (as) that you include in the salam/salawat?
Please show me where the Prophet (saw) made an exception; if he didn’t, why should I?
42:23 That is (the Bounty) whereof Allah gives Glad Tidings to His Servants who believe and do righteous deeds. Say: "No reward do I ask of you for this except the love of those near of kin." And if any one earns any good, We shall give him an increase of good in respect thereof: for Allah is Oft-Forgiving, Most Ready to appreciate (service).
All those followed the path of Hz. Ibrahim (as) are included in salaam/salawaat.
