The Prophet (ﷺ) said, "The most sinful person among the Muslims is the one who asked about something which had not been prohibited, but was prohibited because of his asking."
Sahih al-Bukhari Book 96, Hadith 20
← Previous Hadith The Prophet (ﷺ) said, "Leave me as I leave you, for the people who were before you were ruined because of their questions and their differences over their prophets. So, if I forbid you to do something, then keep away from it. And if I order you to do something, then do of it as much as you can."

Sahih al-Bukhari Book 96, Hadith 19 Next Hadith → The Prophet (ﷺ) took a room made of date palm leaves mats in the mosque. Allah's Messenger (ﷺ) prayed in it for a few nights till the people gathered (to pray the night prayer (Tarawih) (behind him.) Then on the 4th night the people did not hear his voice and they thought he had slept, so some of them started humming in order that he might come out. The Prophet (ﷺ) then said, "You continued doing what I saw you doing till I was afraid that this (Tarawih prayer) might be enjoined on you, and if it were enjoined on you, you would not continue performing it. Therefore, O people! Perform your prayers at your homes, for the best prayer of a person is what is performed at his home except the compulsory congregational) prayer." (See Hadith No. 229,Vol. 3) (See Hadith No. 134, Vol. 8)
