If men were to stay obedient to his parents then they can be his paradise and if they are made angry then the same parents can be his Jahannam.

Until one does not please his parents (after abusing them), his obligatory (Fardh), optional (Nafl) or any action will not be accepted. Together with punishment in the hereafter, he will get torment problems in this world as well. May Allah forbid, it is feared that he will not get a chance to recite the Kalimah at the time of death.

It is stated in a Hadith
“Obidence of Allah is the obidience of the father. Disobidence of Allah is disobidence of the father”. Tibrani – narrated from Hadhrat Abu Hurairah RadiAllahu Anhu

It is stated in another tradition:
“Allah’s pleasures is in the pleasure of the father, and Allah’s displeasure is in the displeasure of the father”. Tirmidhi, Ibn Majah & Hakim narrated by Hadhrat Abdullah ibn ‘Umar.

In a third Hadith related by Hadhrat Abu Ammamah RadiAllah Anhu in Ibn Majah:
“They (parents) are your Paradise and Hell”.

In a fourth Hadith related by Hadhrat Abu Darda RadiAllah Anhu in Tirmidhi & Ibn Majah:
“The father is the most central (middle) door of all doors of Paradise, it is up to you that you may lose it or protect it”.

In a fifth Hadith reported by Hadhrat Abu ‘Umar in Nisai:
“Three people will not enter Paradise – Disobident to parents,
Shameless people,
Women who take the appearance of men”.

In a sixth Hadith reported by Hadhrat Abu Ammama RadiAllahu Anhu in Ibn Abu Asim
“Allah does not accept the Fardh or Nafl from three people:

a) Disobedient person who reminds the taker after giving Charity
b) That person who disbelieves that good deeds and bad deeds are from Allah.
c) Disobedient to his parents.

In a seventh Hadith it is stated stated in Tibrani/Hakim from Hadhrat Abu Bakr RadiAllahu Anhu
“The punishment for all sins, if Allah wills can be suspended until the day of judgement, except the punishment for disobedience of parents – which Allah sends in this lifetime”.
