737. hadíth
وَ رُوِيَ: أَنَّ قَوْماً مُشَاةً أَدْرَكَهُمْ رَسُولُ اَللَّهِ صَلَّى اَللَّهُ عَلَيْهِ وَ آلِهِ فَشَكَوْا إِلَيْهِ شِدَّةَ اَلْمَشْيِ فَقَالَ لَهُمُ «اِسْتَعِينُوا بِالنَّسْلِ ».
It is narrated that a group of people who were walking met the Messenger of Allah (swt) (peace and blessings of Allah (swt) be upon him and his family), and they complained to him about the difficulty of walking. Prophet (saws) said to them: "Seek assistance through walking briskly (nasl)."
