In explaining the testimony of faith, Muslim scholars have listed seven conditions of the shahadah, which a Muslim must fulfill so that s/he may be acknowledging the unity of Allah in open and in secret. 

These seven are:
1.Al-Ilm (Knowledge of the meaning of the shahadah, its negation and affirmation)
2.Al-Yaqeen (Certainty – perfect knowledge of it that counter-acts suspicion and doubt)
3.Al-Ikhlaas (Sincerity which negates shirk)
4.Al-Sidq (Truthfulness that permits neither falsehood nor hypocrisy)
5.Al-Mahabbah (Love of the shahadah and its meaning, and being happy with it)
6.Al-Inqiad (Submission to its rightful requirements, which are the duties that must be performed with sincerity to Allah (alone) seeking His pleasure)
7.Al-Qubool (Acceptance that contradicts rejection).
