Thirdly: Touching the Black Stone and Kissing It
1. The ruling of touching the Black Stone and kissing it
It is sunnah to touch the Black Stone and kiss it.  However, if one performing circumambulation finds that people are struggling with each other to reach it, then one avoids harming others. It is sufficient to point at the Black Stone with one’s hand. This is because struggling harms oneself and others, and harm might occur as a result. It also dissipates humility and dissolves the purpose of circumambulation: worshipping Allah. One might even partake in foul speech, argumentation, or fighting. Consensus on touching the Black Stone being sunnah was related by Ibn Hazm, Ibn `Abd al-Barr, Ibn Rushd, and al-Nawawi.
2. Saying Allahu Akbar at the Black Stone with every round
It is sunnah to say Allahu Akbar whenever touching – or pointing at – the Black Stone in every round.  Saying Bismillah before saying Allahu Akbar has been authentically narrated from Ibn `Umar as his own judgment [i.e. not the Prophet’s ﷺ].

If one does not touch the Black Stone and kiss it, one may touch it and kiss one’s hand, touch it with something in one’s possession and kiss that, or point at it with one’s hand without kissing it.
Fourthly: Touching the Yemeni Corner
It is mustahabb to touch the Yemeni Corner, which is the corner preceding before the Black Stone. One does not kiss it or what one touches it with. Consensus on this was related by Ibn `Abd al-Barr and Ibn Rushd.
Touching other than the two Yemeni corners
It is not sunnah to touch anything other than the two Yemeni corners i.e. the Yemeni Corner and the Black Stone.

The first position: It is mustahabb to recite the Qur’an during circumambulation though received invocation is superior. This is the position of the Hanafi  However, they predicate that it be done quietly, reciting it to himself without raising the voice so as not to disturb others, as this would keep them from supplicating. and Shafi`i schools, one of two narrations from Ahmad, and it was narrated from a group of the Salaf.

2. Where to pray the two units after circumambulation
Praying the two units is legislated to be behind The Station. Al-Nawawi and Ibn Taymiyyah related consensus on this.
3. Those not able to pray the two units behind The Station
If one is unable to offer the two units of prayer after circumambulation behind The Station due to crowds or some other reason, one prays them wherever it is easy to do so anywhere in The Mosque.  Ibn `Uthaymin says: “The mistake here is that some people believe that the two units after circumambulation must be offered behind The Station or close by. The issue is not as they think. Rather, these two units are valid anywhere in The Mosque. Rather, a person may place The Station between them and the Ka`bah even at a distance. In this way, they accomplish the sunnah act without harming those circling the Ka`bah or anyone else.” (Majmu` Fatawa wa Rasa’il Ibn `Uthaymin, 22/413) This is by agreement of the four schools of jurisprudence.
