“The Messenger of Allah ﷺ turned to face the Stone, then he put his lips on it and wept for a long time. Then he turned and saw ‘Umar bin Khattab weeping. He said: ‘O ‘Umar, this is the place where tears should be shed.’” (Using translation from Ibn Mājah 2945)
«اسْتَقْبَلَ رَسُولُ اللَّهِ ﷺ الْحَجَرَ وَاسْتَلَمَهُ ثُمَّ وَضَعَ شَفَتَيْهِ عَلَيْهِ يَبْكِي طَوِيلًا» فَالْتَفَتَ فَإِذَا عُمَرُ يَبْكِي فَقَالَ «يَا عُمَرُ هَا هُنَا تُسْكَبُ الْعَبَرَاتُ»
