Hajj is obligatory immediately when we are able to perform it. Knowledge about basic rules of Hajj and Prayers is must which is simple and can be obtained in short time. Less knowledge about general teachings of Islam does not mean an excuse to postpone Hajj.
You will get more blessings of Hajj as your intention is more sincere to perform this great worship and submit to and follow the Prophet (SAWA) and his Ahlul Bayt (AS).
The sincere performance of Hajj opens gates for more blessings , wealth and knowledge.
