Some of actions, things and measures you must require in advance before starting your journey to holy Hajj.  Some of major prerequisites of hajj we are mentioning under.

1. The pilgrim (Haji) must have genius sincerity and purity towards doing hajj i.e. there must be no other reason except the pleasure of Allah as a result of hajj.

2. Turn away from previous sins, a pure repentance which might never let you do intentional sin in future.

3. You must be able to perform hajj, physically, financially and mentally.

4. The money (Wealth) you are going to spent in Hajj must be halal (Lawful).

5. If you are in debt, you must pay off it before intending toward your hajj journey.

6. Purity also means asking forgiveness from those whom you might have hurt in life or have wronged before you are going to hajj.

7. Write you will and chose the company, travel agency or tour operator which is most trustworthy and righteous as pre-requisites of hajj for having hajj packages.

8. Learn the basic and detailed ruling, rituals and methods to perform hajj and Umrah before taking over from your country as much as possible along with memorizing dua and duas from Quran and Sunnah relevant and irrelevant from Hajj and Umrah.
