question #3 Sahih al-Bukhari 5294, Book 68, Hadith 43 : What is the importance of invoking Allah during prayer for a Muslim seeking good?

Abul Qasim (the Prophet (ﷺ) ) said, “There is an hour (or a moment) of
particular significance on Friday. If it happens that a Muslim is
offering a prayer and invoking Allah for some good at that very
moment, Allah will grant him his request.” (The sub-narrator placed
the top of his finger on the palm of the other hand between the middle
finger and the little one.)
