Hajj & Umrah

Q: Can a hernia patient wear underwear in ihraam?

Q: My father has a small problem with old age and urine drops. He says straight after he goes to the toilet, about 5 or 10 mins after, he has some trouble with few drops. Then it subsides. 

He usually uses tissue with his underwear for a few minutes after going to the bathroom in case any drops come out and then discards it a short while later. 

He's concerned with ihraam and how would he manage. 

What would be suggested? Is there an option to wear underwear and pay damm? Or is there any alternative.

Q: Since only those in ihraam can make tawaaf on the mataaf, would it be considered deception and lying if one has to wear ihraam solely to make tawaaf on the mataaf? Is this form of loophole permissible?

Q: 

1. If one ties the ihram in Masjidul Aqsa but does not make intention for being in ihram, do they get the reward of the virtue given? 

2. Also, if one is traveling from Masjidul Aqsa to Makkah Shareef but has to stop in Riyadh and then travel to Jeddah. What is their ruling on the ihram, can they wear the ihram but not make intention?

Q: With regards to women performing Umrah, I've been advised that it's preferred they make ibaadah individually. However, my question is if a woman has the correct intentions and adopts strict pardah and makes tawaaf and performs salaah in the Haram Shareef, is she rendered sinful in this regard?

Q: Is it permissible for one in the state of ihraam to kill a locust?

Q: I am aware that when a male is in the state of ihraam, then it is necessary for him to leave the shoelace area of the feet uncovered. What about when he is sleeping in the state of ihraam? Can his feet be covered by the duvet or blanket?

Q: Is it permissible to make wudhu or ghusl with Zam-zam water?

Q: Is it necessary to stand and drink Zam-zam?

Q: If my wife is pregnant and is due to give birth during the time when I will be away for my fardh hajj, can I still go for hajj and leave her alone or should I delay my hajj?
