He doubted whether he performed Tawaf-ul-Ifadah or not

Q: I performed Hajj 3 years ago, praise be to Allah. It was Ifrad Hajj (performing Hajj only) and I assumed Ihram (ritual state for Hajj or `Umrah) from the Miqat (site for entering the ritual state for Hajj or `Umrah) in Muharram Valley. I performed two Rak`ahs (units of Prayer) and said Talbiyah (devotional expressions chanted at certain times during Hajj and `Umrah) for Hajj. Then, I went to Makkah and made Tawaf-ul-Qudum (circumambulation of the Ka`bah on arrival in Makkah) and performed two Rak`ahs. I do not remember whether I performed the Sa`y (going between Safa and Marwah during Hajj and `Umrah) or not. On the eighth day I went to Mina and remained there until Fajr (Dawn) Prayer. Then, I moved with the pilgrims to `Arafah where I stayed until sunset. Then, I moved to Muzdalifah and stayed in it until Fajr Prayer. I went to throw Jamarat (stone pillars at which pebbles are thrown during Hajj) and threw Jamarat-ul-`Aqabah (the closest pebble-throwing area to Makkah) and shaved my head. I do not remember whether I performed Tawaf-ul-Ifadah (final obligatory circumambulation of the Ka`bah in Hajj) and Sa`y or not. I stayed the last three days in Mina to throw the Jamarat and after that I went to Makkah and performed Tawaf-ul-Wada` (circumambulation of the Ka`bah on leaving Makkah). Explain to me, may Allah reward you with the best, if I have to complete what I missed of Hajj to rid myself of the doubts? Is it obligatory on me to slaughter a sheep? Should I pay it to one poor person or to more? I want to repeat the Hajj, is this permissible? Which is better; to perform Ifrad Hajj (performing Hajj only), Qiran Hajj (combining Hajj and `Umrah without a break in between) or Tamattu` Hajj (`Umrah during the months of Hajj followed by Hajj in the same year with a break in between), in place of my first Hajj? Answer me, may Allah reward you with the best on me and Muslims!

A: You have to perform Tawaf-ul-Ifadah (final obligatory circumambulation of the Ka`bah in Hajj) and Sa`y (going between Safa and Marwah during Hajj and `Umrah). In addition, if you had sexual intercourse with your wife during this period, you are committed to Dam (atonement required of a pilgrim for a willful violation of a prohibition or obligation while in the ritual state for Hajj and `Umrah). (Part No. 10; Page No. 232) Moreover, you should not approach your wife until you perform Tawaf and Sa`y. If you remain in Makkah after Tawaf-ul-Ifadah (final obligatory circumambulation of the Ka`bah in Hajj) and Sa`y, it is obligatory to perform Tawaf-ul-Wada` (circumambulation of the Ka`bah on leaving Makkah) because the Tawaf you performed previously was misplaced. It was done before Tawaf-ul-Ifadah and the Sa`y. Also, you should repent to Allah for delaying seeking the fatwa throughout this long period. By doing so, your Hajj will be valid. If you want to perform Hajj another time, it is better for you to perform Tamattu` Hajj by performing `Umrah during the months of Hajj. Then, after finishing it, you assume Ihram (ritual state for Hajj or `Umrah) for Hajj on the eighth day with pilgrims. However, there is nothing wrong with performing Ifrad Hajj (performing Hajj only) or Qiran Hajj (combining Hajj and `Umrah without a break in between). However, if you perform Tamattu` Hajj or Qiran Hajj, you will be charged with a Hady (sacrificial animal offered by pilgrims) to be slaughtered in the festival day or during the Days of Tashriq (11th, 12th and 13th of Dhul-Hijjah) in Makkah. Allah Almighty knows best!May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
