Once the people of Quba fought with each other till they threw stones on each other. When Allah's Apostle was informed about it, he said, "Let us go to bring about a reconciliation between them."  

أَنَّ أَهْلَ قُبَاءٍ اقْتَتَلُوا حَتَّى تَرَامَوْا بِالْحِجَارَةِ فَأُخْبِرَ رَسُولُ اللَّهِ ﷺ بِذَلِكَ فَقَالَ اذْهَبُوا بِنَا نُصْلِحُ بَيْنَهُمْ
