۞ لَّقَدْ Certainly رَضِىَ Allah was pleased ٱللَّهُ Allah was pleased عَنِ with ٱلْمُؤْمِنِينَ the believers إِذْ when يُبَايِعُونَكَ they pledged allegiance to you تَحْتَ under ٱلشَّجَرَةِ the tree فَعَلِمَ and He knew مَا what فِى (was) in قُلُوبِهِمْ their hearts فَأَنزَلَ so He sent down ٱلسَّكِينَةَ the tranquility عَلَيْهِمْ upon them وَأَثَـٰبَهُمْ and rewarded them فَتْحًۭا (with) a victory قَرِيبًۭا near ١٨
Certainly was Allāh pleased with the believers when they pledged allegiance to you, [O Muḥammad], under the tree, and He knew what was in their hearts, so He sent down tranquility upon them and rewarded them with an imminent conquest
