Is the prayer of a person who reads something that catches his eye in prayer invalidated?

Dear Brother / Sister,

If a writing in a fiqh, hadith and any other book catches a person’s eye and if he reads it silently, his prayer is not invalidated even if he understands it. There is unanimous agreement on it. However, it is makruh to do such a thing. (Tatarhaniyya – Fatawaw al-Hindiyya)

If the writing on the mihrab is something other than the Quran and if a person reads it silently and understands it, his prayer is invalidated according to Imam Muhammad but it is not invalidated according to Imam Abu Yusuf. The scholars say the ijtihad of Imam Abu Yusuf is preferred. This is the sound view. (al-Hidaya / Marghinani)
