If you are travelling to visit someone or if you are about to receive guests, whether those in question are your parents, relatives, peers or friends of different age, make sure that your hands, feet and socks are clean and your appearance and clothing are neat. Also, ensure that your attire befits the occasion and the one you are meeting, because cleaniness and an apperance which is orderly and harmonious brings pleasure to the eye. Never undermine the importance of your appearance for that would certainly mar the pleasure of the meeting, while dulling the enjoyment of those you meet.
In this regard, the Prophet [Sallallahu álayhi wa sallam] directed his companions upon returning from a journey: “You are on your way to meet your brothers. Don a good dress and repair your conveyance so that you appear distinct among people as a beauty spot (on a body). Allah does not like indecency in manner and conduct.”
Try to offer a gift to your host and likewise present your guests with a present in exchange of theirs because the exchanging of gifts on joyous occasion adds to its delight. A gift, however symbolic, will leave behind happy memories of the occasion. Rasulullah [Sallallahu álayhi wa sallam] said, “Exchange gifts and therefore acquire the gifts of one another.” [Bukhari in Al-Adabul Mufrad]
Our pious predecessors used to leave their host with a gift, even if it was something as simple as a miswák.
