وَالْأَمْنُ وَالْإِيَاسُ يَنْقُلَانِ عَنْ مِلَّةِ الْإِسْلَامِ وَسَبِيلُ الْحَقِّ بَيْنَهُمَا لِأَهْلِ الْقِبْلَةِ
False security from divine punishment and despair of divine mercy are departures from the proper path; for Ahl al-Qibla, the way of truth lies between them.
Amn is disregarding the possibility of accountability, while iyas abandons hope of Allah's mercy. Both harm the believer's religious life.
Faith combines awareness of punishment with hope in divine pardon.
