Unbelief stands on four supports: hankering after whims, mutual quarrelling, deviation from the truth, and dissension. So, whoever hankers after whims does not incline towards right: whoever quarrels much on account of ignorance remains permanently blinded from the right; whoever deviates from truth, for him good becomes evil and evil becomes good and he remains intoxicated with misguidance; and whoever makes a breach (with Allah and His Messenger), his path becomes difficult, his affairs become complicated and his way of escape becomes narrow.
