[Machine] The Messenger of Allah ﷺ used to touch the Yemeni corner and the Black Stone in every circumambulation (tawaf), but he did not touch the other two corners that are opposite to the Black Stone.
أَنَّ رَسُولَ اللهِ ﷺ كَانَ يَسْتَلِمُ الرُّكْنَ الْيَمَانِيَ وَالْأَسْوَدَ كُلَّ طَوْفَةٍ وَلَا يَسْتَلِمُ الرُّكْنَيْنِ الْآخَرَيْنِ اللَّذَيْنِ يَلِيَانِ الْحَجَرَ
