All the Infallibles (a.s.) recited Kalima-e-Tayyeba when they appeared in this world, in which they testified Tauheed of Allah, Risalat of Mohammad (s.a.w.a.w.) and Walayat of Ali (a.s.). Then no doubt our Kalima-e-Tayyeba is:
لا اِلَهَ إِلاَّ اللّهُ مُحَمَّداً رَسُولُ اللّهِ عَلیُِّ وَْلِی اللہِ وَ وَصیُّْ رَسوُلِ اللہ وا خَلیفَۃُ بِلا فَصل
La ilaha illallaho Mohammad-ur Rasool Allah Ali-un Wali Ullah Wasi-o Rasool Allah wa Khalifato hu bila fasl.
To testify Tauheed of Allah, Risalat of Mohammad (s.a.w.a.w.) and Walayat of Infallible Imams (a.s.) is only One Kalima, it can not be subdivided or it has no parts and sections.
In surah Nisa v.59, Allah commands us to obey Allah, Rasool (s.a.w.a.w.) and Olil-Amr (Twelve Infallible Imams a.s.).
So we testify our obedience to these three supreme Authorities in our Kalima by mentioning Allah, His Rasool (s.a.w.a.w.) and His Wali (a.s.).
Imam Jafar Sadiq (s.a.) said about the saying of Allah, ‘Pure Kalima rises towards Allah, and good deed elevates it’ (Fatir 10): ‘Kalima Tayyiba (Pure)’ means the saying of Momin: ‘There is none worthy of worship except Allah, Mohammad (s.a.w.a.w.) is Rasool of Allah, Ali (s.a.) is Wali of Allah, and Khalifa of Rasool Allah.’ And said: Good Deed (Amal e Saleh) means faith with heart that it is Haqq from Allah and there is no doubt about it that it is from the Rabb of Aalameen.
(Tafseer Ali bin Ibraheem, Tooba 18-19)
Shajara-e-Tayyeba
In surah Ibrahim (a.s.) v. 24-25, Allah says that Kalima Tayyiba is like Shajarah Tayyiba [Pure Good (Family) Tree].
“Have you not seen how Allah gives example of Kalima Tayyiba like a Tayyiba Tree whose root is firm and whose branches are in the sky. Yielding its fruit every moment by the permission of it’s Rabb; and Allah gives examples for the people so that they keep doing Zikr.”
(Ibraheem 24-25)
Imam Jafar e Sadiq (s.a.) said: Holy Tree is that tree, its root is Rasool Allah (s.a.w.a.w.), stem is Amirul Momineen (s.a.), and Masomeen (s.a.a.) who are Aal of both of them, are its branches, and the knowledge of Imams (s.a.a.) is its fruit.
According to Imam Sadiq (a.s.), the Root of this Shajarah Tayyiba is Rasool Allah (s.a.w.a.w.), the Stem is Imam Ali (a.s.), the Branches are 11 Infallible Imams (a.s.), the Fruit is their Knowledge.
So it is very simple that Kalima Tayyiba is only that in which whole Tree is mentioned: Allah (the Creator of this Tree), His Rasool (s.a.w.a.w.) and His Wali (a.s.).
