Shahih Bukhari - 687

Telah menceritakan kepada kami [Muhammad bin Salam] berkata, telah mengabarkan kepada kami ['Abdah] dari [Yahya bin Sa'id Al Anshari] dari ['Amrah] dari ['Aisyah] berkata, "Pada suatu malam Rasulullah shallallahu 'alaihi wasallam pernah shalat di kamarnya, saat itu dinding kamar beliau tidak terlalu tinggi (pendek) hingga orang-orang pun melihat Nabi shallallahu 'alaihi wasallam berdiri shalat sendirian. Orang-orang itu pun berdiri dan shalat di belakang beliau, hingga pada pagi harinya orang-orang saling memperbincangkan kejadian tersebut. Kemudian pada malam keduanya beliau kembali shalat, dan orang-orangpun mengikuti shalat beliau kembali. Mereka melakukan ini selama dua atau tiga malam hingga setelah malam itu, Rasulullah shallallahu 'alaihi wasallam duduk di rumahnya dan tidak keluar melaksanakan shalat seperti malam sebelumnya. Pada pagi harinya orang-orang mempertanyakannya, lalu beliau bersabda: "Aku khawatir bila shalat malam itu ditetapkan sebagai kewajiban atas kalian." (HR. Bukhari: 687)

Narrated ʿAisha: Allah's Messenger (ﷺ) used to pray in his room at night. As the wall of the room was LOW, the people saw him and some of them stood up to follow him in the prayer. In the morning they spread the news. The following night the Prophet (ﷺ) stood for the prayer and the people followed him. This went on for two or three nights. Thereupon Allah's Messenger (ﷺ) did not stand for the prayer the following night, and did not come out. In the morning, the people asked him about it. He replied, that he way afraid that the night prayer might become compulsory. (Bukhari: 687)
