عَنْ أَنَسٍ: أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ صَلَّى الظُّهْرَ بِالْمَدِينَةِ أَرْبَعًا وَصَلَّى الْعَصْر بِذِي الحليفة رَكْعَتَيْنِ
Translation

Ibn ‘Abbas said that God’s Messenger used to combine the noon and the afternoon prayer while travelling, and also to combine the sunset and the evening prayer. Bukhari transmitted it.
