Al-Ghazali: The Banes of the Tongue (Book 24 of The Revival of the Religious Sciences)
In the Banes of the Tongue (Kitāb āfāt al-lisān), book 24 of Imām al-Ghazālī’s 40-volume magnum opus, the Revival of the Religious Sciences (Iḥyāʾ ʿulūm al-dīn), al-Ghazālī divides up the banes, or defects, of the tongue from the least to the most offensive, into twenty chapters. These include seemingly mundane acts, such as speaking about what is not our concern, superfluous chatter, pretentious speech, to more serious defects, such as using obscene words, cursing, ridiculing others, making false promises, lying, gossip, and backbiting (even with gestures and looks). Al-Ghazālī carefully defines each defect and analyzes both its psychological and spiritual dimensions. He offers examples of how these banes manifest themselves in behavior, highlighting their effects on others, while outlining the consequences for the soul. Finally, he offers practical suggestions for eliminating these banes, and stresses the devastating nature of their consequences, both in this life and in the next.
