Disobedience of parents –A grave sin
At 2 different times, 2 different questions were put to the Holy Prophet (Sallallahu alaihi wa sallam). One question was that which deed was the most beloved deed with Almighty Allah. The Holy Prophet (Sallallahu alaihi wa sallam) also said: Kind treatment of parents.
The second question was about the major sins. In reply to this, the Holy Prophet (Sallallahu alaihi wa sallam) said: Disobedience of parents.
As is mentioned in this Hadith of Sahih Bukhari:
Translation: It is narrated on the authority of Hadhrat ‘Abdullah bin Mas’ud (May Allah be well pleased with him), he says: I asked the Holy Prophet (Sallallahu alaihi wa sallam): Which is the deed most beloved to Allah Most High? He said: Offering Salaat at its proper time. He then asked: Then which act is most beloved? He said: Kind treatment of parents. He asked: Then which act is the most beloved? He said: Striving in the path of truth. (Sahih Bukhari, Hadith No. 527)
There is another Hadith in Sahih Bukhari:
Translation: It is narrated on the authority of Hadhrat Anas bin Malik (May Allah be well pleased with him), he says: The Holy Prophet (Sallallahu alaihi wa sallam) was asked about major sins. He said: Ascribing partners to Allah, disobeying one’s parents, murdering someone and giving false testimony are major sins. (Sahih Bukhari, Hadith No. 2653)
On committing other sins, Almighty Allah gives that person a respite and the punishment is given in the hereafter, but disobedience of sins is such a grave sin that apart from the hereafter, in this world itself that person will suffer various hardships, tribulations and sorrows.
There is a Hadith in Mustadrak ‘Alas Sahihain:
Translation: It is narrated on the authority of Hadhrat Abu Bakrah (May Allah be well pleased with him), he says: I heard the Holy Prophet (Sallallahu alaihi wa sallam) say: Among all sins, for any sin that He wants to, Almighty Allah may postpone the punishment until the Day of Judgment except disobedience of parents, because Allah Most High punishes the person who is disobedient to his (or her) parents before death right in this world. (Mustadrak ‘Alas Sahihain, Hadith No. 7372; Shua’bul Iman, Hadith No. 7646)
