yep...cuz we normal beings so we cant be compared with Prophet Muhammad PBUH.
but still i gonna answer u....i thought u might gonna bring some other renown pious ppls...such as Hatim Tai, dajjal
but kher.
since we are dealing with normal beings it is not hard to make a note of that people care less about qualities...as we say "Zarooret Ijad ki ma" so we only take note of such things when we are in some problem...so we needs them acc. to our needs, and give the name of fact.
people even use their iman for this purpose.....i doubt i ever hardly see anyone with "blind faith"
otherwise this technique is greatly used a marketing strategy....lol...e.g. samad-dada-bhai ppl...(asking ppl's investing, promising increments n bla bla)
so it is good not to form an absolute-idealized perception of someone.
another thing is we all have our own levels of judgement . sometimes it takes us ages to know a man and sometimes we get to know a person in a nick of a second .
yah we misjudge ppl also overestimate them at times . yah ppl also makes best use of their abilities to overcome their problems . but these abilities can be modified at any stage .
added value is the polish and shine that comes out in use of every ability - that is ure quality.
