In The Name of Allaah, The Most Merciful, The Bestower of Mercy.
Abu Hurairah [radiyallaahu-anhu] narrated that the Messenger [sallal-laahu-alayhi-wasallam] said: “Travelling is a portion of torment. It prevents one of you from your sleep, food, and drink. So when one of you fulfils his (need behind that travelling), then let him hurry back to his family”. [Muslim 1927].
Imaam An-Nawawi [rahimahullaah] commented on this hadeeth that it means: One is prevented from full sleep and its full enjoyment due [to what travelling involves of] difficulties, tiredness, heat and cold, worries, fear, isolation from one family and rough [circumstances]. So, it is recommended that one returns to his family after fulfilling his business and does not delay his return due to something else that is not important.
