People count with self-satisfaction the number of times they have recited the name of God on their prayer beads, but they keep no beads for reckoning the number of idle words they speak.
Al-GhazaliDo not allow your heart to take pleasure with the praises of people, nor be saddened by their condemnation.
Al-GhazaliUnderstand that for every rule which I have mentioned from the Quran, the Devil has one to match it, which he puts beside the proper rule to cause error.
Al-GhazaliIf the first inward thought is not warded off, it will generate a desire, then the desire will generate a wish, and the wish will generate an intention, and the intention will generate the action, and the action will result in ruin and divine wrath. So evil must be cut off at its root, which is when it is simply a thought that crosses the mind, from which all the other things follow on.
