Is there any contradiction between surat Annisa ayat 78 and 79?

I've read about the translation in two different language Indonesia and English between these two ayats 78 and 79 in surah Annisa . I found something that I think it is a contradiction, but I'm not sure myself since the Quran is from our Creator and it is impossible to have a single contradiction. From the ayat 78 : > Wherever you may be, death will overtake you, even if you should be > within towers of lofty construction. But if good comes to them, they > say, "This is from Allah "; and if evil befalls them, they say, "This > is from you." **Say, "All [things] are from Allah** ." So what is [the > matter] with those people that they can hardly understand any > statement? from what I understand this ayat told us that every good or evil that comes to us is From Allah. From the ayat 79 : > **What comes to you of good is from Allah , but what comes to you of > evil, [O man], is from yourself**. And We have sent you, [O Muhammad], > to the people as a messenger, and sufficient is Allah as Witness. this ayat from what I understand that Good is from Allah and evil is from our self. and I check on both ayat there are using the same word which is So if I'm not mistaken it is clear that from ayat 78 Good or Evil comes from Allah, but when I comes to ayat 79 Good is from Allah and Evil is From our self? I'm not an expert on this field, but I like to read quran with their translation so I could understand them. may be I got something wrong with this, so please someone with deep understanding explain this two ayat. thank you.
