Glorification of Allah by a Traveler while Ascending and Descending
وَعَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ أَنَّ رَجُلاً قَالَ: يَا رَسُولَ اللَّهِ ، إِنِّي أُرِيدُ أَنْ أُسَافِرَ فَأَوْصِنِي، قَالَ: "عَلَيْكَ بِتَقْوَى اللَّهِ، والتكبيرعلي كل شرف" فَلَمَّا وَلَّى الرَّجُلُ قَالَ: " اللَّهُمَّ اطْوِ لَهُ الْبعد، وهون عَلَيْهِ السّفر” ((رَوَاهُ التِّرْمِذِيّ وَقَالَ حَدِيث حَسَن)).
Abu Hurairah (May Allah be pleased with him) reported: A man said: "O Messenger of Allah (ﷺ), I intend to set out on a journey, so counsel me." He (ﷺ) said, "Fear Allah, and ascending towards the raised ground, you should recite: "Allahu Akbar (Allah is Greatest)." When the man turned away, he (ﷺ) said, "O Allah! Shorten the distance for him and make the journey easy for him." [At-Tirmidhi].
