Imam Zainul Aabedeen (a.
Imam Zainul Aabedeen (a.s.) has said that if the reason of parent’s right on their children is very much due to the fact that they have done good to him and then the good and the favor which Muhammad and Aale Muhammad (a.s.) have done to this Ummah are much more than those of the biological parents. Therefore both of them are far more entitled to be fathers and more entitled to observation of their right on the Ummah.
Imam Baqir (a.s.) said that a man who knows the honour and respect of his Lord should think as to how much respect and honour he should give to his two noblest fathers Muhammad and Ali (a.s.) and consequently his respect for Allah will be according to his respect to the two honourable persons.
Imam Sadiq (a.s.) said that a man who observes the right of his noblest fathers, Muhammad and Ali (a.s.) even if he had neglected the rights of the biological parents and of all other servants of Allah, will not be harmed because the aforesaid two spiritual parents will, on the day of justice, make his biological parents’ pleased with him.
Imam Moosa Kazim (a.s.) has said that the more rewarding is the Prayer the more the performer of Prayer sends Salawat on his two nobler spiritual fathers Muhammad and Ali (a.s.). Imam Ridha (a.s.) asked: Does anyone of you not dislike that his parents who gave birth to him may not be accepted by people as his parents? They replied: Why not? By Allah, it seems very repugnant.
The Imam said that such a person tries that people should refuse to recognize Muhammad and Ali (a.s.), who are nobler than his biological parents, as his two fathers. Once a man said to Imam Taqi (a.s.): I love Muhammad and Ali (a.s.) so intensely that I cannot stop loving them even if my body is torn apart or cut into pieces with scissors.
The Hazrat replied: They (the holy ones) will reward you according to (in proportion with) your affection for them and they will, on the Day of Qiyamat, plead for high honours and rank for you and that even a little portion of it will be million times greater than the level of your love.
Imam Ali Naqi (a.s.) said that a man in whose sight his two spiritual fathers, Muhammad and Ali (a.s.) will not be more lovable than his biological parents, will not earn any respectability in the view of Allah the Almighty.
