"Abdullah, may Allah be pleased with him, said: "I have not failed to touch these two corners since I saw the Messenger of Allah touching them, the Yemeni Corner and Black Stone, either when it is difficult or when it is easy.'" (Using translation from Nasāʾī 2952)
قَالَ عَبْدُ اللهِ مَا تَرَكْتُ اسْتِلَامَ هَذَيْنِ الرُّكْنَيْنِ مُنْذُ رَأَيْتُ رَسُولَ اللهِ ﷺ يَسْتَلِمُهُمَا الْيَمَانِيَّ وَالْحَجَرَ فِي شِدَّةٍ وَلَا رَخَاءٍ
