Combining Tawaf-ul-Ifadah with Tawaf-ul-Wada`

Q 1: I combined Tawaf-ul-Ifadah (final obligatory circumambulation of the Ka`bah in Hajj) and Tawaf-ul-Wada` (circumambulation of the Ka`bah on leaving Makkah) with one intention for both, is this valid?

A: If you delayed Tawaf-ul-Ifadah and performed it just before you left Makkah and you did not stay (Part No. 10; Page No. 257) in Makkah after performing it, it would serve as sufficient for Tawaf-ul-Wada`. However, if you remained in Makkah after performing Tawaf-ul-Ifadah, you would be obliged to perform Tawaf-ul-Wada` upon leaving Makkah. This is according to what Ibn ‘Abbas (may Allah be pleased with them both) said: The people were ordered to perform Tawaf of the Al-Bayt (the House: another name for the Ka`bah) (i.e. Tawaf-ul-Wada`) as the last thing (they do) before leaving (Makkah), except menstruating women who were excused. Q 2: We used to stay at Mina part of the night from about 10 P.M. Until 3.30 or 4 A.M., is it permissible to do so? A: If you stayed at Mina for most of the night, this is sufficient to fulfill the obligatory stay at Mina.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
