[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  

[Machine] The Messenger of Allah ﷺ used to take these two Yemeni corners every time he passed by them, but would not take the others.  

كَانَ رَسُولُ اللهِ ﷺ يَسْتَلِمُ هَذَيْنِ الرُّكْنَيْنِ الْيَمَانِيَيْنِ كُلَّمَا مَرَّ عَلَيْهِمَا وَلَا يَسْتَلِمُ الْآخَرَيْنِ  

[Machine] The Messenger of Allah ﷺ used to touch the Yemeni corner and the Black Stone, and he wouldn't touch anything else.  

«كَانَ رَسُولُ اللهِ ﷺ يَسْتَلِمُ الرُّكْنَ الْيَمَانِيَّ وَالْحَجَرَ وَلَا يَسْتَلِمُ غَيْرَهُمَا»
