Hadith #443 (Sahih al-Bukhari)
Book: Prayers (Salat)
Narrator(s): Abdullah al-Khaulani
Grade: Sahih

I heard `Uthman bin `Affan saying, when people argued too much about his intention to reconstruct the mosque of Allah’s Messenger (ﷺ), “You have talked too much. I heard the Prophet (ﷺ) saying, ‘Whoever built a mosque, (Bukair thought that `Asim, another sub-narrator, added, “Intending Allah’s Pleasure”), Allah would build for him a similar place in Paradise.’ “
