Al-Adab Al-Mufrad 414
حَدَّثَنَا إِسْمَاعِيلُ بْنُ أَبِي أُوَيْسٍ قَالَ: حَدَّثَنِي مُحَمَّدُ بْنُ هِلاَلِ بْنِ أَبِي هِلاَلٍ مَوْلَى ابْنِ كَعْبٍ الْمَذْحِجِيِّ، عَنْ أَبِيهِ، أَنَّهُ سَمِعَ أَبَا هُرَيْرَةَ قَالَ: سَمِعْتُ النَّبِيَّ صلى الله عليه وسلم يَقُولُ: لاَ يَحِلُّ لِرَجُلٍ أَنْ يَهْجُرَ مُؤْمِنًا فَوْقَ ثَلاَثَةِ أَيَّامٍ، فَإِذَا مَرَّتْ ثَلاَثَةُ أَيَّامٍ فَلْيَلْقَهُ فَلْيُسَلِّمْ عَلَيْهِ، فَإِنْ رَدَّ عَلَيْهِ السَّلاَمَ فَقَدِ اشْتَرَكَا فِي الأَجْرِ، وَإِنْ لَمْ يَرُدَّ عَلَيْهِ فَقَدْ بَرِئ الْمُسْلِمُ مِنَ الْهِجْرَةِ.

Abu Hurayra reported that he heard the Prophet (may Allah bless him and grant him peace) say: It is not lawful for a man to shun a believer for more than three days. When three days have passed, let him meet him and greet him. If he returns the greeting, they share in the reward; if he does not, the Muslim has discharged himself of the estrangement.
Notes and open questions — unreviewed
The Arabic says the Muslim who initiates the greeting is cleared of the estrangement if the other does not return it.
