On some occasions, the devotee boasts about himself in his speech

 "On some occasions, the devotee boasts about himself in his speech; while expressing the purity of his soul, he makes a display of his devotional exercises, brags about himself by mentioning his pious deeds, and denounces others for their shortcomings, thus highlighting the superiority of his piety. Sometimes he does not say anything explicitly but makes some gesture, which implicitly exhibits his piety. A scholar afflicted with kibr may brag about his own intellectual achievements, saying, “What do you know!" Then he would mention the books read and written by him, the universities visited by him, the professors and authorities whom he has met, and his own scholarly endeavors. Therefore, at all times, it is necessary to seek refuge in God from the mischiefs of the self and its wiles."
