فَإِذَا قُضِيَتِ الصَّلَاةُ فَانتَشِرُوا فِي الْأَرْضِ وَابْتَغُوا مِن فَضْلِ اللَّهِ
“And when the prayer has been concluded, disperse within the land and seek from the bounty of Allah.”
Surah Al-Jumu'ah 62:10 legislates the core structure of Salat al-Jumu'ah -- hastening to the prayer and dispersing to seek Allah's bounty afterward -- the very practice this event marks the historical institution of: the first Salat al-Jumu'ah ever prayed in Islam, led by Mus'ab ibn Umayr RA in Yathrib before the Prophet ﷺ's own arrival.
