Q:
What is the ruling on saying Isti`adhah (seeking refuge with Allah from Satan) and Basmalah (saying, "Bismillah Al-Rahman, Al-Rahim [In the Name of Allah, the Most Gracious, the Most Merciful]") before the Adhan (call to Salah)?
A:
We know of no basis affirming that it is permissible for a Mu'adhin (caller to Prayer) or a person who hears the Adhan to say Isti`adhah and Basmalah before Adhan. It is authentically narrated that the Messenger of Allah (peace be upon him) said,
Anyone who does an action which is not in accordance with this matter of ours (Islam) will have it rejected.
In another narration,
Anyone who introduces anything into this matter of ours (Islam) that is not part of it will have it rejected.
(Part No. 6; Page No. 99) May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
