Qom- DarolErfan/ the researcher, exegete and scholar of holy Quran emphasized on performing the duties that human beings are responsible for and said: do not split the religion of Allah into pieces, If Muslims, like Christians and Jews, cut off the teachings of Moses and Jesus (AS), and do the duties which are easy and simple but do away with acts and deeds that are hard, this is not religion, but this is playing with religion and making fun of the religion.
Professor Ansarian said: In the surah of Mobarakeh Yunus, Allah has said:
أَلاٰ إِنَّ أَوْلِیٰاءَ اَللّٰهِ لاٰ خَوْفٌ عَلَیهِمْ وَ لاٰ هُمْ یحْزَنُونَ اَلَّذِینَ آمَنُوا وَ کٰانُوا یتَّقُونَ
Indeed, there shall be neither fear nor sorrow upon the guided by Allah. Those who believe and are cautious.
The divine prophets and the real believers have worshiped Allah until the last moment of their lives and have avoided the sins and forbidden deeds as well. This is the real meaning of piety that the real believers have lived their lives while permanently, continuously and constantly worshiping Allah and avoiding the forbidden deeds and sins.
And finally professor Ansarian explained the meaning of duty which Allah Almighty asked his servants to do: he went on to say that duty means offering a series of issues that are good for our world and our Hereafter and guarantee our eternal happiness and salvation by Allah Almighty, Prophet Muhammad (PBUH) and the infallible Imams (AS). Some of these duties are obligatory and some of them are good, and it leads to perfection and growth; that is why the Lord of the universe has obligated us to accept the duties of himself, of his prophet (PBUH) and of the infallible Imams(AS);
أَطِیعُوا اَللّٰهَ وَ أَطِیعُوا اَلرَّسُولَ وَ أُولِی اَلْأَمْرِ مِنْکمْ
Believers, obey God, His Messenger, and your (qualified) leaders.
