Fataawa al-Hajj wal-‘Umrah waz-Ziyaarah p77
Question: Is it permissible for one performing the Hajj or the ‘Umrah, whilst performing the tawaaf, to enter the Hajar Ismaa’eel?
Response: It is not permissible for one performing tawaaf of the House (Ka’bah) during the Hajj or the ‘Umrah or voluntary tawaaf to enter the Hajar Ismaa’eel. He is not rewarded for that if he does so because the tawaaf is required around the House and the Hajar is part of the House, for that which Allaah سبحانه و تعالى says:
Also, that which is narrated by Muslim and others on the authority of ‘Aa’ishah (radhi-yAllaahu ‘anhaa) who said: “I asked the Messenger of Allaah ﷺ regarding the Hajar and he said:
”
And in another wording, she said: “I vowed to pray inside the House and he ﷺ said:
“.
And with Allaah lies all success and may Allaah send prayers and salutations upon our Prophet ﷺ and his family and his companions.
