Mishkat al-Masabih 19 Jihad كتاب الجهاد 115

وَعَنْ جَابِرٍ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسلم: «إِذا طَال أَحَدُكُمُ الْغَيْبَةَ فَلَا يَطْرُقْ أَهْلَهُ لَيْلًا»

Jabir reported God’s Messenger as saying, “When one of you has been away from home for a long time he must not come to his family during the night.” (Bukhari and Muslim.)
