Kissing the Ka’bah is not prescribed in sharee’ah
Question

Is kissing the Holy Ka’bah during the rituals of Hajj or ‘Umrah halal or haram?.
Praise be to Allah.What is prescribed is to kiss the Black Stone. It was proven that the Prophet (peace and blessings of Allah be upon him) kissed the Black Stone, but he did not kiss any other part of the Holy Ka’bah. 
And Allah is the Source of strength. May Allah send blessings and peace upon our Prophet Muhammad and his family and companions. End quote.
