Focused on the Ruling (Missed Tawaf)

You went straight to the hotel after performing Tawaf, and there you realized that you had not offered the Nawafil (supererogatory prayers) at Maqam Ibrahim (Station of Abraham). Firstly, you were supposed to offer the Nawafil at Maqam Ibrahim, within Masjid al-Haram (the Grand Mosque). When you didn't even offer them, how did you just get up and leave on your own? If your Tawaf was a Nafl (optional) one, and one performs the Nawafil after the Tawaf, then there is no issue. But, if this was the Tawaf for your Umrah, then your Umrah is incomplete. However, I think that Sa'ee (the ritual walking) is compulsory after the Tawaf of Umrah. I hope that this was your Nafl Tawaf. May Allah Almighty grant you reward and forgive what was missed. Amen
