We might not need anything but the Opening of the Noble Book, the Fatiha, and another sura or two, particularly that on the Divine Unity, the sura called Ihklas – Sincerity.
If we do go further, we start with the first sura of the Qur’an after the Opening, Sura al-Baqara.
It begins with an account of the people of Taqwa, a word which it is impossible to translate as piety, but whose root meaning is to protect oneself. This word says “Danger! Beware! Be careful!” Taqwa is held to contain all good.
The second part consists of two ayats that deal with unbelievers and dismisses them magisterially.
The third is extensive and is about those who lyingly claim to believe in God and the Last Day but do not. In other words, these are Muslims who are not what they seem.
Then after the account of Adam, peace be upon him, a substantial section addresses the story of the Tribe of Israel in some detail. This leads into the passages that begin to treat first the subject of spending and giving to others, and then with its opposite, usury. In that context, the longest ayat of the Book of Allah occurs, that pertains to debt/credit. In addition to personal debts, it regulates the matters of taking delivery of goods and paying for them later, and paying in advance and taking delivery of goods at a later date. These two are the basis of much commerce.
The sura concludes with ayats believed to have been revealed during the Ascent to heaven of the Messenger of Allah, peace be upon him, in his face to Face meeting with the Lord of Existence, and, unlike the rest of the revelation, not through the agency of the angel Jibril, peace be upon him. There in the Divine presence, the Messenger, may Allah bless him and grant him peace, did not forget us, but prayed for his umma, with a prayer that is beloved to all the believers and which it is recommended to include in one’s Isha prayer if one can:
Our Lord, do not take us to task if we forget or make a mistake! Our Lord, do not place on us a load like the one You placed on those before us! Our Lord, do not place on us a load we have not the strength to bear! And pardon us; and forgive us; and have mercy on us. You are our Master, so help us against the people of the unbelievers. (2:286)
