I recently performed Salat al-Istikhara (prayer of seeking guidance) regarding a job opportunity in another city. After the prayer, I didn't receive a clear sign or dream, but I felt a sense of calm about the decision. How should one interpret the results of Istikhara when there's no obvious sign? Are subtle feelings or a sense of peace considered valid outcomes? I'd appreciate insights from those who have experience with Istikhara and how to discern its results.
