The Messenger of Allah ﷺ combined the noon and afternoon prayers, and the sunset and night prayers at Medina without any danger and rain. He was asked: What did he intend by it ? He replied: He intended that his community might not fall into hardship. (Using translation from Abū Dāʾūd 1211)
جَمَعَ رَسُولُ اللهِ ﷺ بَيْنَ الظُّهْرِ وَالْعَصْرِ وَالْمَغْرِبِ وَالْعِشَاءِ فِي الْمَدِينَةِ مِنْ غَيْرِ خَوْفٍ وَلَا مَطَرٍ قُلْتُ لِابْنِ عَبَّاسٍ لِمَ فَعَلَ ذَلِكَ؟ قَالَ كَيْ لَا يُحْرِجَ أُمَّتَهُ
