Dear Beyond Tradition
A common understanding that heaven is present under the feet of ones mother or that the mother is more important than the father by three times, is not supported by the Quran.
No husband, wife, father, mother or anyone has the power to appoint heaven to a soul except God.
You will realize from the Quran that a husband can be a disbeliever and the wife a believer and vice versa. You will also notice from the Quran there is an example of a father that is a believer and the son is a disbeliever and vice versa. The examples are Pharaoh and his wife. Prophet Lot and his wife. Prophet Noah and his son. Prophet Abraham and his father.
Also the Quran warns people that their maybe enemies amongst their spouses and children. (64:16). A common translation of the term "Azwajikum" is wives. However this is not the case. Please see article [2] below.
64:16 O ye who believe! Truly, among your SPOUSES and your children are (some that are) enemies to yourselves: so beware of them! But if ye forgive and overlook, and cover up (their faults), verily Allah is Oft-Forgiving, Most Merciful.
As you may notice that such claims are obviously unwarranted and is irrational from a logical perspective.
No one can grant Heaven to anyone only The Almighty Lord Himself.
However as you will appreciate and I'm sure you know that one should not forget that the Quran also does require that kindness, love, goodness, charity, justice, generosity etc should be enjoined from children to parents and husbands to wives and human to human and vice versa.
