Hadith 517850
Chapter 54: General Subjects - كتاب الاستئذان
وَحَدَّثَنِي مَالِكٌ، عَنْ سُمَىٍّ، مَوْلَى أَبِي بَكْرٍ عَنْ أَبِي صَالِحٍ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " السَّفَرُ قِطْعَةٌ مِنَ الْعَذَابِ يَمْنَعُ أَحَدَكُمْ نَوْمَهُ وَطَعَامَهُ وَشَرَابَهُ فَإِذَا قَضَى أَحَدُكُمْ نَهْمَتَهُ مِنْ وَجْهِهِ فَلْيُعَجِّلْ إِلَى أَهْلِهِ " .
Malik related to me from Sumayy, the mawla of Abu Bakr from Abu Salih from Abu Hurayra that the Messenger of Allah, may Allah bless him and grant him peace, said, "Travelling is a portion of the torment. It denies you your sleep, food, and drink. When you have accomplished your purpose, you should hurry back to your family."
