‘Umar said that God’s messenger used to seek refuge in God from five things:

cowardliness, niggardliness, the evils of old age, evil thoughts, and the punishment in the grave. Abu Dawud and Nasa'i transmitted it.

وَعَنْ عُمَرَ قَالَ: كَانَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَتَعَوَّذُ مِنْ خَمْسٍ: مِنَ الْجُبْنِ وَالْبُخْلِ وَسُوءِ الْعُمُرِ وَفِتْنَةِ الصَّدْرِ وَعَذَابِ القَبرِ. رَوَاهُ أَبُو دَاوُد وَالنَّسَائِيّ
