Messenger of Allah ﷺ said, "When anyone of you is away from his house for a long time, he should not return to his family at night."  

قَالَ رَسُولُ اللَّهِ ﷺ إِذَا أَطَالَ أَحَدُكُمُ الْغَيْبَةَ فَلاَ يَطْرُقْ أَهْلَهُ لَيْلاً  

It has been narrated on the authority of Anas b. Malik that the Messenger of Allah ﷺ would not come (back) to his family by night. He would come to them in the morning or in the evening.  

أَنَّ رَسُولَ اللَّهِ ﷺ كَانَ لاَ يَطْرُقُ أَهْلَهُ لَيْلاً وَكَانَ يَأْتِيهِمْ غُدْوَةً أَوْ عَشِيَّةً
