Answer: It will be against the sunnah as to spend the night in Mina on the 8th Zhil Hijjah is sunnah, however if one did not spend the night in Mina, rather stayed elsewhere and proceeded to Arafah, there will be no Dum.

Answer: Staying in Aziziah does not render the same thawaab as staying in Mina.  Mina is a mubarak place, it's boundaries which have been demarcated by Allah cannot be expanded nor reduced. The reward of staying in Mina is immense

Answer: Makkah is independent from Aziziah and like wise Aziziah is independent from Mina. Since you will be staying less than 15 days in Makkah,  you will be a musafir in Makkah, Aziziah and in Mina.

Answer: Under no circumstances is juma allowed in Arafah. Juma is allowed in Mina on condition the Khalifa or his appointed deputy performs the juma. This is not found in current times,  hence juma is not valid in Mina. Performing juma in small congregations in tents or even as a big jamaat in Mina is not valid. Zuhr salaah has to be performed. 

Answer: You will be a muqeem in Makkah as you intend to stay for 15 days, hence full salaah will be performed. When you intended to under take a journey of 77km or more you become a musafir and your status as a muqeem is nullified.  Upon returning to Makkah from Jeddah, you will now be a musafir as your stay in Makkah is less than 15 days.

Answer: According to the Hanafi Mazhab, tarteeb, meaning sequence of pelting, slaughter, shaving the head is waajib. This sequence cannot be disrupted. If this sequence is not adhered to strictly, dum becomes waajib. By entrusting the Saudi Agency to do the dum, this sequence is definitely broken as one will not know when the dum was done, hence entrust a reliable person to do your dum e shukr after pelting and before shaving your head. 

Answer: It is sunnah to leave Mina before the sun sets on the 12th. If this is not possible then there is no harm nor sin to stayover after sunset on the 12th. Only if one is still in Mina at the time of Subh Sadiq of the following day, then pelting of the 13th becomes waajib. There is no dum for staying over in Mina after Maghrib on the 12th.

Answer: If the crowds are excessive and it's difficult to spend the night in Muzdillifah, then women are allowed not to sleep over,  they may return to Mina or their respective accommodation.  Men who accompany their women back to Mina or their respective accommodation need to return to Muzdilifah and spend the time in Muzdilifah between Fajr and sunrise, otherwise dum will be waajib upon the men.

Answer: Only if the elder is so frail that he is unable to walk to the jamaraat nor is there any conveyance that can take him. Excessive crowds are not a justifiable reason to appoint someone else to pelt on one's behalf. If the crowds are excessive , then delay the pelting until the evening or evening around midnight. By delaying the pelting until the evening or midnight does not render a dum. 

Answer: If a woman did not pelt due to fear of crowds then fidya is waajib

Answer: Make your tawaaf e ziyaarah when you are clean,  even if it's after the 12th and no dum is waajib.

Answer: No, tawaaf Wida will not be valid if the intention is made to run concurrently with tawaaf e ziyaarah.  Two separate tawaafs need to be done. 

Answer: It is not a requirement to have Wudhu when making Saee. Saee without wudhu is valid and no penalty is warranted. 

Answer: Make your 2 rakaats salaah of tawaaf at home. No dum nor any penalty is warranted. 

Answer: Tawaaf Wida is waajib and to omit a waajib act renders a dum, unless there is a valid reason,  e.g.  a woman experiences her haidh and there is no option to delay her departure, then the Tawaaf Wida is waived. Likewise,  a person becomes so sick that he cannot even walk to the mataaf to make the tawaaf and there is no means of anyone carrying him nor does he have the physical  strength to sit on a wheel chair and he cannot delay his departure, then this tawaaf will be waived and no dum will be necessary. 

Answer: Giving Dum means to sacrifice a sheep or goat as an expiation for committing a violaition during hajj or umrah. The animal must be sacrificed within the boundaries of the Haram and a monetary substitute cannot be made. A dum does not have to be sacrificed immediately,  upon return to one's home the money can be sent to a reliable person who would be able to discharge the obligation of making the dum, however unnecessary delay in doing the dum is sinful.

Answer: One cannot proceed beyond the Meeqat enroute to Makkah without going into ihram. If you feel that by going into ihram and waiting out your stay in Makkah until you are clean will be very difficult and there is fear that you will be committing various ihram violations then you may proceed to Makkah without ihram and a dum becomes waajib for this violation. After your haidh, you may go to Musjid Aisha and put on ihram and proceed to complete your umrah.

Answer: As long as there is continuity of the saffs from within the Musjid, you may follow the Imam. However if there is a break in the saffs once it overflows out side then the salaah behind the imam will not be valid for those who are performing outside the musjid. A gap of 2 saffs is regarded as a break in continuity and if this is found outside the musjid then the salaah of those behind the break is not valid behind the imam.

Answer: It is not permissible to let the niqaab touch the face. In this case  a sun hat or headgear could be worn in such a way that the niqaab is suspended over the hat so that it does not touch the face. However  if this becomes cumbersome whereby there is danger of tripping, etc then due to the great fitnah  prevalent during hajj and umrah,  the niqaab should be strictly worn at all times.  If it touches the face and the face is covered for less than a day or night then only  sadaqah should be given.
