This is translated as, not upon the path on those whom anger is thrown and those who are lost.
Separation of truth from falsehood:
In the above verses we asked Allah (subhanahu wa ta’ala) to guide us to the right path and in this verse we are asking him to keep us away from the wrong paths. This concept of affirmation and negation is found throughout the Quran, even in our Kalima (lailaha – we negate, illallah – we affirm). This is to ensure that we understand the truth clearly and if we didn’t know the falsehood, the truth may not have been understood clearly. We wouldn’t know the righteous path we were asking Allah’s (subhanahu wa ta’ala) guidance for if we didn’t know the path of “maghdoob” and of “dalleen”.
Ascribing only good to Allah (subhanahu wa ta’ala):
Notice that in Surah Al-Fatihah we didn’t mention about the anger of Allah (subhanahu wa ta’ala) at all. According to a hadith, Prophet Muhammad (sallallahu alaihi wasallam) said we do not ascribe evil to you O Allah (subhanahu wa ta’ala). We only ascribe good to you. When Adam (alaihissalam) and Iblees committed sins, Adam (alaihissalam) ascribed the sin to himself (even though he knew that it couldn’t happen without the will of Allah (subhanahu wa ta’ala)), but Iblees blamed Allah (subhanahu wa ta’ala) for it. Hence a righteous man ascribes the sins to himself and only the good to Allah (subhanahu wa ta’ala).
In this verse when we refer to the people who are shown anger and who are lost it doesn’t mean that Allah (subhanahu wa ta’ala) has forced his anger on them or there is any injustice. It’s those people who deserve anger, who deserve to be lost.
