What are the places where prayers are answered in the Sacred Mosque (Al-Haram Al-Makki), and are prayers answered after drinking Zamzam water?

It is recommended to drink Zamzam water and drink one's fill from it, and it has been narrated that the Prophet (peace be upon him) drank from it. It has also been narrated from the Prophet (peace be upon him) that Zamzam water is for whatever it is drunk for. It is sunnah for the drinker to say when drinking: "Bismillah, O Allah, make it for us beneficial knowledge, ample provision, thirst-quenching and satisfying, and a cure from every disease, and wash my heart with it and fill it with Your wisdom." And it is hoped that the supplication will be answered after drinking it.
