Keep renewing your faith because it is bound to deteriorate
The Messenger of Allah ﷺ said, "Īmān (faith) wears out (deteriorates) within ˹the depths˺ of each one of you just as worn out clothing has been worn out. Therefore, ask Allah to renew Īmān in your hearts."
قَالَ رَسُولُ اللَّهِ ﷺ «إِنَّ الْإِيمَانَ لَيَخْلَقُ فِي جَوْفِ أَحَدِكُمْ كَمَا يَخْلَقُ الثَّوْبُ الْخَلِقُ، فَاسْأَلُوا اللَّهَ أَنْ يُجَدِّدَ الْإِيمَانَ فِي قُلُوبِكُمْ»
