﴿ وَأَطِيعُوا۟ ٱللَّهَ وَرَسُولَهُۥ وَلَا تَنَٰزَعُوا۟ فَتَفْشَلُوا۟ وَتَذْهَبَ رِيحُكُمْ ۖ وَٱصْبِرُوٓا۟ ۚ إِنَّ ٱللَّهَ مَعَ ٱلصَّٰبِرِينَ ﴾

“And pay heed unto God and His Apostle, and do not [allow yourselves to] be at variance with one another, lest you lose heart and your moral strength desert you. And be patient in adversity: for, verily, God is with those who are patient in adversity.”

(And obey Allah and His messenger) in the matter of war, (and dispute not one with another) regarding war (lest ye falter) lest fear strikes you (and your strength depart from you) i.e. you are defeated; (but be steadfast!) in war along with your Prophet (Lo! Allah is with the steadfast) He helps the steadfast in war.
