1. Is there a Hajj Akbar?
If Arafat is on a Friday, then many describe it as Hajj Akbar (Big Hajj). There is no big or small Hajj. There is only one Hajj. Every year is Hajj Akbar. The 10th day of Dhul Hijja is described in The Qur'an as Yaum-ul-Hajjil-Akbar.
3. Can I smoke when I'm in Ihram?
No. Try to give up this habit for the good of your health and the well-being of your family. Many chain smokers have returned from the Hajj as non-smokers for good. Alhamdulillah.
5. Can I perform the Hajj every year?
There is no rule prohibiting anyone from performing the Hajj more than once.
If you plan to perform it yearly, you are obviously financially well endowed. You should consider the following. One, there are other things you can do in the way of Allah. Consider contributing your Hajj trip funds to uplift downtrodden Muslims. Two, with nearly 2 1/2 million people converging in The Sacred Land, the Saudi authorities have understandably imposed quotas. Have a heart for those waiting in line to perform the Hajj for the first time. Allow a reasonable time gap before going to perform the Hajj again.
6. Is it a must for a wife to seek her husband's permission to perform the obligatory Hajj?
Yes. A husband is strongly advised not to object as his wife is seeking permission to perform a duty commanded by The Almighty. Obedience to the command of The Almighty supersedes everything else, including a husband's objection.
7. More tawaaf or more nafl salat?
If you're NOT a local resident, do more tawaaf as Masjid Al Haram is the only place where you can do tawaaf.
8. Multiple Umrah during Hajj/Umrah?
There is no basis for this in the Sunnah or in the practice of the Sahabah.
