Umar Ibn Al Khattab (May Allah be pleased with him) narrated, Prophet (صَلَّى اللّٰهُ عَلَيْهِ وَسَلَّمَ) said: “Faith is to believe in Allah, His Angels, His Books, His messengers, and to believe in Day of resurrection and to believe in destiny, In It’s both good and bad aspects.” (Sahih Al Bukhari and Sahih Muslim).
