Hajj & Umrah

Q: 

1. A lady in haidh had entered into ihram, entered Makkah, then thought that her haidh was over (no bleeding for two days) so she completed the rites of Umrah. She then started bleeding again and realised that her haidh was still continuing. 

What should she do after her haidh has completed? 

Will she need to go to tan'eem and renew her ihraam as well? 

Was her coming out of ihraam valid such that using scented items etc. would not require any compensation? 

2. She performed a nafl tawaaf during that time as well (wherein she was actually still in haidh), what should she do in this case?

Q: I have planned to go for Umrah in July 2025 along with my mother (age 62 years). We will go together and perform Umrah together. But after that, my mother will stay at the house of her own sister's daughter. She will stay there for 15 days. Meanwhile, I will return alone after performing Umrah. She will also return alone from Makkah to Delhi and I will pick her up from Delhi Airport. Whether, returning alone from Makkah to Delhi for my mother is permissible.

Q: During tawaf on the first floor there are times where construction barriers are blocking off certain areas. It is such that we have to walk diagonally where our shoulder moves away from the Kaabah and it seems like our back is facing the Kaabah (but we can't be certain because we can't see the Kaabah from the first floor). It happens few times during tawaaf. What should we do in this situation?
