Hajj & Umrah

Q: Is it permissible to read the two rakaats after tawaaf after Fajr and Asr?

Q: My grandmother has an umrah trip planned for end of March. But her husband passed away a few days ago (Feb 11). I am aware that iddat is for 4 months ten days but my grandma is 75 years old and I wanted to know if she is able to go to umrah and complete the remainder of her iddat when she gets back or is it not permissible for her to go? I was not aware if age makes a difference. 

Q: If someone forgot to perform Saee on 10th Zul Hijjah, he performed all other Hajj Pillars and left Makkah. He came to know later about his mistake. Will his Hajj be invalid? What he should do now to amend his mistake and make his Hajj valid?

Q: A girl has a step mother, can her husband take his step mother in law for Hajj/Umrah? Is he considered as a mahram?

Q: Nowadays even the guards in the Haram Shareef are telling the people to wear towels if they want to access the mataaf, even though they aren't in the state of ihraam.

My question is, in this situation, will one wear the topi or not?

Q: In Musjid Nabawi صلي الله عليه وسلم, there is an app which allows a person to enter the Rowdhatul Jannah once a month by making a booking. What is common is to cancel the booking after the guards check, allowing one to book for a second time in the next week. Is it fine to do this, or will it be considered as deceiving the people of Madinah Munawwarah?

Furthermore, when in Makkah Shareef, one is only allowed to make Tawaaf on the Mataaf if in performing Umrah and in the state of Ihraam. What many do, is wear the Ihraam to Tawaaf on the Mataaf. Is this permissible?

Q: I am traveling from Qatar to perform umrah but I have got my periods and I can’t wait until my periods are over as we have our flights booked. What can I do?

Q: I have 200ml zamzam water. I have 25l normal water. If I put 1 cap zamzam water in the 25l water, will it be effective as the original zamzam water? I'm intending to use it for a jinn possessed person and also reciting and blowing over the water before drinking. 

Q: I heard many people say, including my husband, that when Allah pak will call you that's when you will perform Umrah but I wanted to know that if you don't have the intention of going, don't have your mind set, ain't done your preparation of going, how can you say your not ready because Allah did not call you, when I didn't even put any efforts myself.

If applying for the visa and then the visa gets rejected will be more like Allah pak does not what you to come yet. Is this right or wrong? Do you need to make the niyyat for anything before you can say that Allah did not want you to do this etc?

Q: A woman is currently in Makkah Mukarramah. She has completed her umrah etc. and she spotted just once after Zuhr Salaah. Since then, she has not seen any blood or spotting and more than 24 hours have passed. She has completed more than 15 days of tuhr and it could be her haidh. What does she do? Can she perform tawaaf in this condition?
