I had a question about dua, that I'm looking for some clarification. From my understanding, verse 2:186 mentions whenever dua is made, it is always answered... but in Sahih Hadith (https://sunnah.com/abudawud/5/66) specifically the last third of night is mentioned for dua/supplication being answered. If ayat in quran mentions that whenever any dua is made, it is heard/answered, why does hadith specify only night supplication for answered dua/prayer?
