السَّلامُ عَلَيْكُمْ وَ رَحْمَةُ الله وَ بَرَكات
اَلْمُؤْمِنُ غِر كَرِيْم
The Believer is Simple and Noble
غِر Means one who is deceived easily.
In this hadith it means that one who is pious is of a soft disposition and he trusts upon everyone, that is why he so easily deceived by people.
Or it could be that he thinks good of everyone, and no matter what anyone tells him, he believes them.
He constantly remembers the hereafter, so that if anyone tells him something he believes it, and he forgives those who hurt or deceive him, keeping in mind the reward fro forgiving in the hereafter, so he does not take revenge upon anybody.
It has been mentioned in ahadeeth regrading forgiveness, that on the day of judgement a caller will announce that whom so ever has reward that is by Allah stand up and enter jannah.
Muhammad (sallallahu alayhi wassalam) was asked: "Oh messenger of Allah! Who will these people be?"
He (sallallahu alayhi wassalam) said: "The one who forgave people"
This why a believer is simple and noble, that even though he may be deceived he keeps in front of him the rewards of the hereafter and forgives those harm him.
May Allah (Subhanahu wa ta'ala) instill in us the characteristics of the pious. Ameen.
وَ عَلَيْكُمْ السَّلامْ وَ رَحْمَةُ اللهِ وَ بَرَكات
