Our writing often finds errors in writings in public places. Seems reasonable indeed if the error is in the form of typos, stay or excess letters and so on. But if the error does not come from error (from ignorance) it is strange, because normally before we write a foreign word we must first check it in the dictionary or on google.
Actually it is not wrong that we blame, nor does it force people to be obliged to know everything, but when we write a foreign language at least we first check it right or not, after all the word "silent" is not a rare word we see. The problem here is that the word "silent" is a foreign language, why does the author not once arise doubts, but even very confident and steady with the writing.
In essence, if "silent" is so foreign to him, what about "Cylant" friend? Isn't that more foreign than the foreign world? Or maybe he never hesitated or questioned the right writing, but strangely he also did not doubt the word "cylant".
Often problems like this have undermined us not only among those with low educational backgrounds. But it also happens in educational institutions though. Just look in many cases for mistakes in writing the name of the student both in the absence, report card or diploma. Moreover, if the student's name is taken from Arabic vocabulary.
It's a shame to see a fundamental mistake like this, not without reason, mistakes that are typographical errors or mistakes may be forgiven, but in the case of Muhammad's name being Muhammat (ending with T), Rahmat becomes Rahmad (ending with D), we can assume how the weakness of the Arabic language ability it possesses, even though the word rahmatan lil'alamin alone can be a reference that there is a Grace indeed it must end with T (Rahmatan). Similarly, Muhammad can be seen from the sound of the sentence shahada (wa asyhadu anna muhammadu) and not muhammatu.
In this case, I'd love to ask "don't you have a little doubt when deciding to write T-D?" If there is, why not learn first. Come on, guys, please, not only because we are majoring in mathematics or chemistry, we forget the basic abilities we must have as educated people
