Quran 48:18 — Surah Al-Fath, ayah 18

۞لَّقَدۡ رَضِيَ ٱللَّهُ عَنِ ٱلۡمُؤۡمِنِينَ إِذۡ يُبَايِعُونَكَ تَحۡتَ ٱلشَّجَرَةِ فَعَلِمَ مَا فِي قُلُوبِهِمۡ فَأَنزَلَ ٱلسَّكِينَةَ عَلَيۡهِمۡ وَأَثَٰبَهُمۡ فَتۡحٗا قَرِيبٗا

Certainly was Allah pleased with the believers when they pledged allegiance to you, [O Muhammad], under the tree, and He knew what was in their hearts, so He sent down tranquillity upon them and rewarded them with an imminent conquest

Allah je zadovoljan onim vjernicima koji su ti se pod drvetom na vjernost zakleli. On je znao šta je u srcima njihovim, pa je spustio smirenost na njih, i nagradiće ih skorom pobjedom
