"I was harsh in the way I spoke to my family, but not to others. I mentioned that to the Prophet (saas) and he said: 'Why don't you ask for forgiveness? Ask Allah to forgive you, seventy times each day.'" (Using translation from Ibn Mājah 3817)   

كَانَ فِي لِسَانِي ذَرَبٌ عَلَى أَهْلِي وَلَمْ يَكُنْ يَعْدوُهُمْ إِلَى غَيْرِهِمْ فَسَأَلْتُ النَّبِيَّ ﷺ فَقَالَ «أَيْنَ أَنْتَ مِنَ الِاسْتِغْفَارِ؟ إِنِّي لَأَسْتَغْفِرُ اللَّهَ كُلَّ يَوْمٍ مِائَةَ مَرَّةٍ»
