It is narrated in Sahih Muslim as well as many other sources that:
Someday (after his last pilgrimage) the Messenger of Allah (S) stood to give us a speech beside a pond which is known as Khum (Ghadir Khum) which is located between Mecca and Medina. Then he praised Allah and reminded Him, and then said: "O’ people! Behold! It seems the time approached when I shall be called away (by Allah) and I shall answer that call. Behold! I am leaving for you two precious things. First of them is the book of Allah in which there is light and guidance...The other one is my Ahlul-Bayt. I remind you in the name of Allah about my Ahlul-Bayt. I remind you in the name of Allah about my Ahlul-Bayt. I remind you in the name of Allah about my Ahlul-Bayt. (three times)."

So what about those who fought against ahlubayt and those who neglect them?! They are like people leaving the boat and drawning.
