professor Ansarian:
there is no one in the whole universe whose affection toward human is like the Allah Almighty,s affection and kindness toward human. based on this affection, Allah has granted the human with two types of Aliments which these aliments are mentioned both in the holy Quran and the narrations and supplications. One aliments of the lord of the universe is material which is an apparent and obvious one. And another aliment of the Almighty Allah is the spiritual one. The messenger of Allah peace and blessings of Allah be upon him while explaining the spiritual aliment said: the spiritual aliment is the kindness and the guardianship of the Ahlul bayt peace be upon them, and having the affection and love of Imam Ali and accepting his guardainship is above all according to narrations.
Having fed with the above mentioned aliments as well as the instructions and advices of Allah almighty and the infallible Imams, one can undoubtedly reach the salvation and felicity of both this world and the hereafter.
