Allah's Messenger (ﷺ) said, "Someone came to me from my Lord and gave me the news (or good tidings) that if any of my followers dies worshipping none (in any way) along with Allah, he will enter Paradise." I asked, "Even if he committed illegal sexual intercourse (adultery) and theft?" He replied, "Even if he committed illegal sexual intercourse (adultery) and theft."
Sahih al-Bukhari Book 23, Hadith 1
← Previous Hadith Allah's Messenger (ﷺ) during his illness prayed in his house sitting, whereas some people followed him standing, but the Prophet (ﷺ) beckoned them to sit down. On completion of the prayer he said, "The Imam is to be followed. So, bow when he bows, and raise your head when he raises his head." (See Hadith No. 657 Vol 1 for taking the verdict).

Sahih al-Bukhari Book 22, Hadith 14 Next Hadith → Allah's Messenger (ﷺ) said, "Anyone who dies worshipping others along with Allah will definitely enter the Fire." I said, "Anyone who dies worshipping none along with Allah will definitely enter Paradise."
