question #1 Sahih Muslim 509b, Book 4, Hadith 298 : Why might a person choose to pray near a specific location or object in a mosque?

Salama sought to say prayer near the pillar which was by that place where copies of the Qur’an were kept. I said to him: Abu Muslim. I see you striving to offer your prayer by this pillar. He said: I saw the Messenger of Allah (ﷺ) seeking to pray by its side.
