No, there is no adhaan or iqaamah for them. If you do wudoo’ and then pray as much as you like, such as Salaat al-Duhaa, or after Zuhr, or in the last part of the night, or at any other time, apart from the times when salaah is not allowed, these prayers are to be done without adhaan or iqaamah. It was not narrated that when the Messenger of Allaah (peace and blessings of Allaah be upon him) stood up to pray [any optional prayer], he gave the adhaan or the iqaamah. The adhaan and iqaamah are only for the obligatory prayers. But for Taraaweeh, Witr and other optional prayers, there is no adhaan or iqaamah, as the scholars have stated, and as is the Sunnah of the Messenger of Allaah (peace and blessings of Allaah be upon him) and the Khulafaa’ al-Raashideen.
And Allaah knows best.
