سورة الأنعام

Ali ibn Ibrahim (may Allah have mercy on him): وَ لاَ تَقْرَبُواْ مَالَ الْیَتِیمِ إِلاَّ بِالَّتِی هِیَ أَحْسَنُ [And do not approach the property of the orphan except in the best manner] — that is, with kindness and without extravagance.

Imam Sadiq (peace be upon him): Abdullah ibn Sinan narrates: My father asked Imam Sadiq (peace be upon him), and I was present there. He said: "When do the affairs and transactions of the orphan become valid?" He said: "When he reaches maturity (bulugh)." He said: "When is his maturity?" He said: "When he becomes muhtalim (has a nocturnal emission)." He said: "Sometimes a boy up to eighteen years, or less or more, does not become muhtalim." He said: "When he becomes an adult and sins and good deeds are recorded for him, his affairs and transactions are valid, unless he is foolish or weak of intellect."

Imam Sadiq (peace be upon him): Imam Sadiq (peace be upon him) said: "When a boy reaches maturity, that is, thirteen years, and enters his fourteenth year, whatever is obligatory upon those who have become muhtalim also becomes obligatory upon him, whether he has become muhtalim or not, and his sins and good deeds are recorded for him, and disposal of his wealth is permissible for him, unless he is foolish or weak."

Imam Baqir (peace be upon him): Jabir narrates: Imam Baqir (peace be upon him) said: The Commander of the Faithful (peace be upon him) was among you in Kufa, and every day at the beginning of the morning he would go out from Dar al-Imara (the governor's residence) and go around the markets of Kufa one by one. With him, upon his shoulder, was a whip which had two ends and was called "Sabiba." He would stand before the people of each market and call out: "O company of merchants! Adopt the fear of Allah." When they heard his voice, they would throw down what they had in their hands and give their hearts and souls to his words, and listen with their ears as he said: "Put seeking good from Allah first [before buying and selling], and seek blessing through easy dealing in transactions, and draw close to the buyers (do not sell at high prices, for they will flee from you), and adorn yourselves with the ornament of forbearance and patience, and refrain from swearing oaths, and keep away from lying, and stay far from oppression, and treat the oppressed with fairness. And do not take usury. And وَ أَوْفُوا الْکَیْلَ وَ الْمِیزانَ وَ لا تَبْخَسُوا النَّاسَ أَشْیاءَهُمْ وَ لا تَعْثَوْا فِی الْأَرْضِ مُفْسِدِینَ [give full measure and weight with justice, and do not diminish anything of people's property, and do not act corruptly on the earth, causing mischief]." He would go around all the markets of Kufa, then return and sit down to attend to the affairs of the people.

Imam Ali (peace be upon him): Washika said: I saw Ali (peace be upon him) wearing a lower garment, the upper part of which reached above his navel and its cloth reached halfway down his shins, and he had a whip in his hand and was going around the market and saying: "Fear Allah and give full measure with justice." It was as if he were a teacher of children.
