Prayer: Doubting the Conditions for the Exception of Adhan and Iqamah
Practical Laws of Islam as per the teachings of Ayatullah Sistani
Ruling 912
If a person has a doubt about the third condition mentioned above, i.e. he doubts whether or not the congregational prayer is valid, then saying adhān and iqāmah is excepted for him. However, if he has a doubt about one of the five other conditions, it is better that he say adhan and iqamah; but if his prayer is in congregation, he must say them with the intention of rajaʾ.
