"Two men disagreed over the Masjid whose foundation was laid upon Taqwa from the first day (9:108). A man said: 'It is Masjid Quba' and the other said: 'It is the Masjid of the Messenger of Allah (ﷺ).' So the Messenger of Allah (ﷺ) said: 'It is this Masjid of mine.'"
Jami` at-Tirmidhi Book 47, Hadith 151
← Previous Hadith "'Abdullah bin 'Abdullah bin Ubayy came to the Messenger of Allah (ﷺ) when his father died, and said: 'Give me your shirt to shroud him in and perform the Salat upon him, and seek forgiveness for him.' So he (ﷺ) gave him his shirt, and said: 'When you are finished then inform me.' So when he wanted to perform the Salat, 'Umar tugged at him and said: 'Has not Allah prohibited that you perform Salat over the hypocrites?' He said: 'I have been given the choice between two: 'Whether you seek forgiveness for them or you do not seek forgiveness for them.... (9:80)' So he performed the Salat for him. Then Allah revealed: 'And never pray for any of them who dies, nor stand at his grave... (9:84)' So he abandoned praying for them."

Jami` at-Tirmidhi Book 47, Hadith 150 Next Hadith → that the Prophet (ﷺ) said: "This Ayah was revealed about the people of Quba: In it are men who love to purify themselves. And Allah loves those who make themselves pure (9:108)." He said: "They used water to perform Istinja so this Ayah was revealed about them."
