If you know that it is to be acquired, this will cause you to be constantly grateful. (Tenvir, 6)
Everything that is desired is called a blessing (niʿma). However, in ḥaqīqa (inner reality), the true blessing is the happiness of the hereafter. Nevertheless, it is permissible to call other things blessings as well. All these states, in relation to us, are divided into four: The first are those that are beneficial both in the dunyā (this world) and in the hereafter, such as knowledge and good character. This is the true blessing. The second are those that are harmful in both. These are truly afflictions. The third are those that are beneficial now but harmful later, such as pleasures and shahwa (carnal desires).
According to people of understanding, this is an affliction, but the ignorant think it is a blessing. Its example is as follows: When a hungry person finds honey that contains poison, if he does not know there is poison in it, he thinks it is a blessing. If he knows, he considers it an affliction. The fourth are those that are harmful now but beneficial in the end. According to people of intellect, this is a blessing; to the ignorant, it is an affliction. (Kudāma, 299)
