Reciting Takbeer When Ascending And Tasbeeh When Descending

During the journey, when ascending any place, one should recite takbeer (الله اكبر) , and when descending any place, one should recite tasbeeh (سبحان الله)

قال جابر رضي الله عنهما : كنا إذا صعدنا كبرنا , وإذا نزلنا سبحنا (بخاري رقم 2993)

Hazrat Jaabir (Radhiyallahu Anhuma) reports that we, (the Sahaabah [Radhiyallahu Anhum], during our journeys) would recite takbeer while ascending, and recite tasbeeh while descending.
