Janabe Fatema Zehra (S.A.) said to Imam Husain (A.S.):
"When you were born Prophet of Islam (S.A.W.) came to me and took you in his arms and then said, ‘O Fatema! take Husein (A.S.) and know that he will be father of nine Imams and from his progeny will come guided Imams of whom the ninth one will be QAEM.’"(Isbatul Huda, Vol. 2, Pg. 552)
