[Machine] The Messenger of Allah ﷺ said, "Migration is not permissible for more than three days. If they meet, then one of them should greet the other with peace. If the other refuses to return the greeting, he is free from sin and the other incurs it. I consider, he said, that if they both die while they are migrants, they will not be reunited in Paradise."  

قَالَ رَسُولُ اللَّهِ ﷺ «لَا تَحِلُّ الْهِجْرَةُ فَوْقَ ثَلَاثَةِ أَيَّامٍ فَإِنِ الْتَقَيَا فَسَلَّمَ أَحَدُهُمَا عَلَى الْآخَرِ فَرَدَّ عَلَيْهِ الْآخَرُ السَّلَامَ اشْتَرَكَا فِي الْأَجْرِ وَإِنْ أَبَى الْآخَرُ أَنْ يَرُدَّ السَّلَامَ بَرِئَ هَذَا مِنَ الْإِثْمِ وَبَاءَ بِهِ الْآخَرُ وَأَحْسِبُهُ قَالَ وَإِنْ مَاتَا وَهُمَا مُتَهَاجِرَانِ لَا يَجْتَمِعَانِ فِي الْجَنَّةِ»
