الفتح — Al-Fath Ayat 18
۞ لَقَدْ رَضِيَ اللّٰهُ عَنِ الْمُؤْمِنِيْنَ اِذْ يُبَايِعُوْنَكَ تَحْتَ الشَّجَرَةِ فَعَلِمَ مَا فِيْ قُلُوْبِهِمْ فَاَنْزَلَ السَّكِيْنَةَ عَلَيْهِمْ وَاَثَابَهُمْ فَتْحًا قَرِيْبًاۙ
Laqad raḍiyallāhu ‘anil-mu'minīna iż yubāyi‘ūnaka taḥtasy-syajarati fa‘alima mā fī qulūbihim fa'anzalas-sakīnata ‘alaihim wa aṡābahum fatḥan qarībā(n).
"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"
