He only has enough
    money for two people to go for Hajj – him and his wife, or his father and mother
Question

                Assalamu alaikum.My wife and I are planning to go for Hajj next year. Shall I send my
      parents first before we go? None of us have done Hajj before.I don't have provision for all four of us to go together for Hajj.My question is: Who goes first? My wife and I, or my parents?Jazakallahu Khair,Assalamu alaikum.
Praise be to Allah.The Muslim is not obliged to pay for his wife or either of his parents
    to go for Hajj, because his duty with regard to his wife and parents is to spend on their
    food, drink, clothing and shelter. But if a Muslim wants to donate the cost of going to
    Hajj to anybody, he should start with his mother, then his father, then his wife, because
    of the hadeeth of Abu Hurayrah (may Allaah be pleased with him), according to which a man
    came to the Messenger of Allaah 
 (peace and blessings of Allaah be upon him) and said,
    O Messenger of Allaah, who is most deserving of my good treatment? He said,
    Your mother. He asked, Then who? He said, Your mother.
    He asked, Then who? He said, Your mother. He asked, Then
    who? He said, Your father. Ibn Shubrumah and Yahyaa ibn Ayyoob said: Abu
    Zurah told us something similar. (Reported by al-Bukhaari, 5514). And Allaah knows best.
