Zayd bin Thabit reported,

The Messenger of Allah ﷺ prayed one night, and the people in the mosque heard his prayer. The next night, more people gathered, but the Messenger of Allah's ﷺ voice was faint to them, so they began trying to draw his attention by clearing their throats.The Messenger of Allah ﷺ looked out at them and said, "You have kept on doing what you are doing until I feared it might be made obligatory upon you. If it were made obligatory upon you, you would not be able to keep it up. The best prayer a person performs is in his own home, except for the prescribed prayer."

حدثنا محمد بن بشر حدثنا محمد بن عمرو حدثني موسى بن عقبة عن أبي النضر عن بسر بن سعيد

عن زيد بن ثابت قال

صلى رسول الله ﷺ ليلة فسمع أهل المسجد صلاته قال فكثر الناس الليلة الثانية فخفي عليهم صوت رسول الله ﷺ فجعلوا يستأنسون ويتنحنحون قال فاطلع عليهم رسول الله ﷺ فقال ما زلتم بالذي تصنعون حتى خشيت أن يكتب عليكم ولو كتبت عليكم ما قمتم بها وإن أفضل صلاة المرء في بيته إلا صلاة المكتوبة
