Iyas bin Amir says: Sayyiduna Ali bin Abi Talib (may Allah be pleased with him) held my hand and then said: If you live (long enough, you will see that) three types of people will recite the Qur'an: one group will recite the Qur'an for Allah, one group for argument and debate, and one group will recite it for the world, and whoever recites it for worldly gain will attain what he seeks.
