Quran Al-Anfal 8:46
وَأَطِيعُواْ ٱللَّهَ وَرَسُولَهُۥ وَلَا تَنَٰزَعُواْ فَتَفۡشَلُواْ وَتَذۡهَبَ رِيحُكُمۡۖ وَٱصۡبِرُوٓاْۚ إِنَّ ٱللَّهَ مَعَ ٱلصَّٰبِرِينَ ٤٦
Translation
And obey Allāh and His Messenger, and do not dispute and [thus] lose courage and [then] your strength would depart; and be patient. Indeed, Allāh is with the patient.
