Hazrat Fatimah al-Zahra (a)
إنْ كُنْتَ تَعْمَلُ بِمَا أَمَرْنَاكَ وَ تَنْتَهِي عَمَّا زَجَرْنَاكَ عَنْهُ فَأَنْتَ مِنْ شِيعَتِنَا وَ إِلاَّ فَلاَ
If you are performing whatever we have ordered with, and keeping away from what we deter you from, then you are of our Shias, otherwise you are not of our Shias.
Bihar al-Anwar, v. 65, p. 154
