Surah Taha — Ayah 64 (20:64)
فَأَجۡمِعُواْ كَيۡدَكُمۡ ثُمَّ ٱئۡتُواْ صَفّٗاۚ وَقَدۡ أَفۡلَحَ ٱلۡيَوۡمَ مَنِ ٱسۡتَعۡلَىٰ ٦٤
English translation (Saheeh International)
So resolve upon your plan and then come [forward] in line. And he has succeeded today who overcomes."
Brief commentary
So make a firm decision and do not differ therein. Then go forward in rows and throw down what you have all at once. Whoever defeats his opponent today has attained his objective.
