The Prophet ﷺ said, "Paradise is closer to one of you than the strap of his sandal, and the Fire is just as close."
قال النبي ﷺ: الجنة أقرب إلى أحدكم من شراك نعله، والنار مثل ذلك.
Bukhari narrated it in the Book of Riqaq (6488), from Musa bin Masud, who said, "Sufyan narrated to us, from Mansur and Amash, from Abu Waail, from Abdullah," and he mentioned it.
