Answered by Sidi Mostafa Azzam
What is it recommended to do if one is leading after one’s fatiha when one is silent to allow those behind one to recite their fatiha?
Answer:

It is recommended for the imam to recite to himself Qur’an or du`a’, and Qur’an is better (Kashifat al-Saja, 69 (Dar al-Fikr).)
