Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) said: "Whoever among you recites the Qur'an should also learn the fara'id (the rules of inheritance). For if a Bedouin meets him and says: O Muhajir, do you recite the Qur'an? He will say: Yes. The Bedouin will say: I recite too. Then the Bedouin will ask: Do you know the fara'id, O Muhajir? If he says: Yes, the Bedouin will say: You have something extra and good. But if he says: I do not know it, the Bedouin will say: Then what superiority do you have over me, O Muhajir?"
