Conditions & Fundamentals of Hajj and Umrah

Reciting the talbiyah after passing the meeqaat

Q: I performed umrah a couple of days ago. I was travelling from Madina to Makkah and I was sure ( i had نیت in my heart) about umrah. At Dhul-Hulaifah I put on two sheets (dress of ehraam) and offered two rakat nafil but I forget to say TALBIYA.

I departed for Makkah after performing nawafil of ehraam and after 5-10 minutes travelling I remembered about talbiya and I said the talbiya and niyat by tongue then and there. Is my umrah correct or do I have to pay any penalty/sadaqah?

Performing umrah when entering Makkah Mukarramah after leaving the meeqaat

Q: I intend performing umrah next week Wednesday. I will be staying in Makkah for 5 days i.e. Wednesday to Sunday. I will be returning home on Monday. Am I allowed to visit Madinah just to convey my Salaam to Nabi (sallallahu alaihi wasallam) for just one day (Saturday) and return back to Makkah without donning ihram or performing another umrah again?
