The word(s) "duties" appears 11 time(s) in 11 verse(s) in Quran in Mohsin Khan translation.

(1) It is He Who has sent down to you (Muhammad صلى الله عليه وسلم) the Book (this Qur'an). In it are Verses that are entirely clear, they are the foundations of the Book [and those are the Verses of Al-Ahkam (commandments), Al-Fara'id (obligatory duties) and Al-Hudud (legal laws for the punishment of thieves, adulterers)]; and others not entirely clear. So as for those in whose hearts there is a deviation (from the truth) they follow that which is not entirely clear thereof, seeking Al-Fitnah (polytheism and trials), and seeking for its hidden meanings, but none knows its hidden meanings save Allah. And those who are firmly grounded in knowledge say: "We believe in it; the whole of it (clear and unclear Verses) are from our Lord." And none receive admonition except men of understanding. (Tafsir At-Tabari).

(2) And they said nothing but: "Our Lord! Forgive us our sins and our transgressions (in keeping our duties to You), establish our feet firmly, and give us victory over the disbelieving folk."

(3) O you who believe! Betray not Allah and His Messenger, nor betray knowingly your Amanat (things entrusted to you, and all the duties which Allah has ordained for you).

(4) Verily, Allah enjoins Al-'Adl (i.e. justice and worshipping none but Allah Alone - Islamic Monotheism) and Al-Ihsan [i.e. to be patient in performing your duties to Allah, totally for Allah's sake and in accordance with the Sunnah (legal ways) of the Prophet صلى الله عليه وسلم in a perfect manner], and giving (help) to kith and kin (i.e. all that Allah has ordered you to give them e.g., wealth, visiting, looking after them, or any other kind of help), and forbids Al-Fahsha' (i.e all evil deeds, e.g. illegal sexual acts, disobedience of parents, polytheism, to tell lies, to give false witness, to kill a life without right), and Al-Munkar (i.e all that is prohibited by Islamic law: polytheism of every kind, disbelief and every kind of evil deeds), and Al-Baghy (i.e. all kinds of oppression). He admonishes you, that you may take heed.

(5) Then let them complete their prescribed duties (Manasik of Hajj) and perform their vows, and circumambulate the Ancient House (the Ka'bah at Makkah).

(6) That (Manasik- prescribed duties of Hajj is the obligation that mankind owes to Allah), and whoever honours the sacred things of Allah, then that is better for him with his Lord. The cattle are lawful to you, except those (that will be) mentioned to you (as exceptions). So shun the abomination (worshipping) of idol, and shun lying speech (false statements) -

(7) Those who are faithfully true to their Amanat (all the duties which Allah has ordained, honesty, moral responsibility and trusts) and to their covenants;

(8) Verily, the Muslims (those who submit to Allah in Islam) men and women, the believers men and women (who believe in Islamic Monotheism), the men and the women who are obedient (to Allah), the men and women who are truthful (in their speech and deeds), the men and the women who are patient (in performing all the duties which Allah has ordered and in abstaining from all that Allah has forbidden), the men and the women who are humble (before their Lord - Allah), the men and the women who give Sadaqat (i.e. Zakat, and alms), the men and the women who observe Saum (fast) (the obligatory fasting during the month of Ramadan, and the optional Nawafil fasting), the men and the women who guard their chastity (from illegal sexual acts) and the men and the women who remember Allah much with their hearts and tongues Allah has prepared for them forgiveness and a great reward (i.e. Paradise).

(9) Truly, We did offer Al-Amanah (the trust or moral responsibility or honesty and all the duties which Allah has ordained) to the heavens and the earth, and the mountains, but they declined to bear it and were afraid of it (i.e. afraid of Allah's Torment). But man bore it. Verily, he was unjust (to himself) and ignorant (of its results).

(10) Verily, there is for you by day prolonged occupation with ordinary duties.
