عَنْ حُذَيْفَةَ رَضِيَ اللَّهُ عَنْهُ قَالَ كَانَ فِي لِسَانِي ذَرَبٌ عَلَى أَهْلِي لَمْ أَعْدُهُ إِلَى غَيْرِهِمْ وَفِي رِوَايَةٍ وَكَانَ ذَلِكَ لَا يَعْدُوهُمْ إِلَى غَيْرِهِمْ فَذَكَرْتُ ذَلِكَ لِلنَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ قَالَ أَيْنَ أَنْتَ مِنَ الِاسْتِغْفَارِ يَا حُذَيْفَةُ إِنِّي لَأَسْتَغْفِرُ اللَّهَ كُلَّ يَوْمٍ مِائَةَ مَرَّةٍ وَأَتُوبُ إِلَيْهِ قَالَ فَذَكَرْتُهُ لِأَبِي بُرْدَةَ بْنِ أَبِي مُوسَى يَعْنِي الْأَشْعَرِيَّ رَضِيَ اللَّهُ عَنْهُمَا فَحَدَّثَنِي عَنْ أَبِي مُوسَى أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ قَالَ إِنِّي لَأَسْتَغْفِرُ اللَّهَ كُلَّ يَوْمٍ وَلَيْلَةٍ مِائَةَ مَرَّةٍ وَأَتُوبُ إِلَيْهِ
It is narrated from Sayyiduna Hudhayfah (may Allah be pleased with him), he says: There was sharpness and corruption in my tongue, but it was only related to my family members, it did not go beyond them. When I mentioned this matter to the Noble Prophet (peace and blessings be upon him), he (peace and blessings be upon him) said: Hudhayfah! Why do you stay away from seeking forgiveness? I seek forgiveness from Allah and turn to Him in repentance one hundred times every day. When I related this to Abu Burdah bin Abi Musa, he narrated to me from Sayyiduna Abu Musa (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: Indeed, I seek forgiveness from Allah and turn to Him in repentance one hundred times every day and night.
