Shaykh ibn ‘Uthaymeen [may Allāh have mercy on him] said:
“O’ my [beloved] brothers: Complete the [blessed] month of Ramadān repenting to Allāh from your sins and turn to Him with actions which are pleasing to Him. Certainly, mankind is not free from error(s) and has deficiencies. All the children of Ādam [عَلَيْهِ السَّلاَم] sin and the best of them are those who repent [constantly].”
