Sheikh-ul-Islām Ibn Taymiyyah (رحمه الله) mentioned in his Majmū’:
“The (truly) fortunate one (is he who) seeks forgiveness for the mistakes, and is patient upon the calamities, just as Allāh says: {So be patient. Verily, the Promise of Allāh is true, and ask forgiveness for your fault}in [Sūrah Ghāfir 40:55].”
