الركن اليماني
The Yemeni Corner (Rukn al-Yamani) is the southwestern corner of the Kaaba, facing Yemen. It is sunnah to touch it with the right hand during tawaf without kissing it. Between the Yemeni Corner and the Black Stone, pilgrims recite the dua: 'Rabbana atina fid-dunya hasanatan wa fil-akhirati hasanatan wa qina adhab an-nar.'
The Yemeni Corner is one of the four corners of the Kaaba, named because it faces the direction of Yemen. It rests on the original foundations laid by Prophet Ibrahim (AS), unlike some other parts of the Kaaba which were modified over time. The Prophet Muhammad (PBUH) used to touch this corner during tawaf, establishing it as a sunnah practice. Abdullah ibn Umar (RA) was particularly known for never missing touching both the Yemeni Corner and the Black Stone.
The Yemeni Corner stands on the original Ibrahimic foundations of the Kaaba. Touching it is an established sunnah. The stretch between the Yemeni Corner and the Black Stone is a particularly blessed segment of tawaf, where a specific Quranic dua is recommended.
During tawaf, try to touch the Yemeni Corner with your right hand as you pass. Do not kiss it or say 'Allahu Akbar' when touching it (this is specific to the Black Stone). If the crowd prevents you from reaching it, continue without pointing toward it (unlike the Black Stone where pointing is sunnah). Between this corner and the Black Stone, recite the recommended dua from Surah Al-Baqarah 2:201.
