From Sahih Bukhari (Hadith 1600):
Narrated Isma'il bin Abu Khalid:`Abdullah bin Abu `Aufa said, "Allah's Messenger (ﷺ) performed the `Umra. He performed Tawaf of the Ka`ba and offered two rak`at behind the Maqam (Abraham's place) and was accompanied by those who were screening him from the people." Somebody asked `Abdullah, "Did Allah's Messenger (ﷺ) enter the Ka`ba?" `Abdullah replied in the negative
