Quran 49:15 – Doubt After Belief
Any doubt that does not impact your actions, behavior and answering to the call of a living Prophet is not mentioned here. Right after that it talks about some serious actions that one has to take. Also, the reality of doubts in the presence of a Prophet of God is very different than when the Prophet is gone.
In this Ayah Allah SWT describing the qualities of a momin. If you see the previous ayah Allah says the Bedouins were Muslims not momin. Hadith Jibreel also describes this difference. قَالَتِ الۡاَعۡرَابُ اٰمَنَّا ؕ قُلۡ لَّمۡ تُؤۡمِنُوۡا وَ لٰکِنۡ قُوۡلُوۡۤا اَسۡلَمۡنَا وَ لَمَّا یَدۡخُلِ الۡاِیۡمَانُ فِیۡ قُلُوۡبِکُمۡ ؕ وَ اِنۡ تُطِیۡعُوا اللّٰہَ وَ رَسُوۡلَہٗ لَا یَلِتۡکُمۡ مِّنۡ اَعۡمَالِکُمۡ شَیۡئًا ؕ اِنَّ اللّٰہَ غَفُوۡرٌ رَّحِیۡمٌ ﴿۱۴﴾
Please see: Discussion 41768 • Reply 41783 “…are we being told to stop thinking” Not every doubt is worth investigating. We’re being stopped from doubts that are purposeless. Once we understand the big picture from the information that is already at our disposal, for every doubt that we investigate further, we should be clear in a) is there any objective purpose that our investigation will serve, and b) do we have any means in human sources of knowledge to reach a reasonable answer . If the response to either one these questions is in negative, the only purpose that will be served by our insistence on finding the answer will be wasteful intellectual entertainment. Since there’s no limit to human imagination, such doubts lead us astray and away from the very essence of the subject. We should also be aware of the fact that certain doubts are only as a result of devil’s whispers. Quran is very clear in multiple instances where certain purposeless doubts should not be entertained.
