Question: Some of the pilgrims, when they approach the line placed as a sign for the beginning of the tawaaf [in line with al-Hajar al-Aswad], they stand there for a long time preventing the[ir] brothers [and sisters] from proceeding with their tawaaf. So, what is the ruling regarding standing on this line and making a long supplication?
Response: Standing on this line for a long time is not required, rather, the person should face al-Hajar al-Aswad and make a sign [with the palm of the right hand] towards it and recite Allaahu Akbar and then proceed, since this is not a place to stand for a long time. However, I see some people standing and saying: “I have made the intention for the Sake of Allaah, the Almighty, to make seven circuits [of the Ka’bah] or tawaaf for ‘Umrah, or voluntary tawaaf”, or that which is similar to this. This is a mistake in the intention, since we have warned that making a verbal intention in acts of worship is an innovation which has not been mentioned on the authority of the Prophet (sal-Allaahu ‘alayhi wa sallam) nor any of his companions (radhi-yAllaahu ‘anhum). So you must perform your acts of worship for the Sake of Allaah (Subhaanahu wa Ta’aala) and He has [complete] knowledge of your intention, so there is no need to verbally do so.
