The ruling on the imam reciting the Basmala aloud

Question:
If the imam recites the Basmala aloud, is there any sin on him? And should he be advised against it?

Answer:
Yes, there is no harm, because some of the Shafi'i scholars hold that it is part of al-Fatihah; in their madhhab, they consider the Basmala to be part of al-Fatihah and that it should be recited aloud just as al-Fatihah is recited aloud. However, the correct view is contrary to this, as you have heard. Yes. Honorable Shaykh. In the mushafs, you will find some with the number one written on the Basmala and some without the number one, due to the disagreement over whether the Basmala is part of al-Fatihah or not.
