كتاب الاستئذان
The Book of Asking Permission
بَابُ مَنْ لَمْ يُسَلِّمْ عَلَى مَنِ اقْتَرَفَ ذَنْبًا، وَلَمْ يَرُدَّ سَلاَمَهُ حَتَّى تَتَبَيَّنَ تَوْبَتُهُ، وَإِلَى مَتَى تَتَبَيَّنُ تَوْبَةُ الْعَاصِي:
(21) Chapter. He who does not greet a person who has committed a sin, and the one who does not reply to his greeting till the evidence of his repentance becomes obvious. And up to what time limit (one should wait for) till the repentance of a sinner is known.
Hadith 6255
حَدَّثَنَا ابْنُ بُكَيْرٍ ، حَدَّثَنَا اللَّيْثُ ، عَنْ عُقَيْلٍ ، عَنِ ابْنِ شِهَابٍ ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ عَبْدِ اللَّهِ بْنِ كَعْبٍ ، أَنَّ عَبْدَ اللَّهِ بْنَ كَعْبٍ ، قَالَ : سَمِعْتُ كَعْبَ بْنَ مَالِكٍ ، يُحَدِّثُ حِينَ تَخَلَّفَ عَنْ تَبُوكَ ، " وَنَهَى رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ عَنْ كَلَامِنَا ، وَآتِي رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَأُسَلِّمُ عَلَيْهِ ، فَأَقُولُ فِي نَفْسِي هَلْ حَرَّكَ شَفَتَيْهِ بِرَدِّ السَّلَامِ أَمْ لَا ؟ حَتَّى كَمَلَتْ خَمْسُونَ لَيْلَةً ، وَآذَنَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ بِتَوْبَةِ اللَّهِ عَلَيْنَا حِينَ صَلَّى الْفَجْرَ " .
Narrated `Abdullah bin Ka`b: I heard Ka`b bin Malik narrating (when he did not join the battle of Tabuk): Allah's Apostle forbade all the Muslims to speak to us. I would come to Allah's Apostle and greet him, and I would wonder whether the Prophet did move his lips to return to my greetings or not till fifty nights passed away. The Prophet then announced (to the people) Allah's forgiveness for us (acceptance of our repentance) at the time when he had offered the Fajr (morning) prayer.
