Silsilah as-Sahihah 4103 — Proclaiming takbir on high places

Abu Huraira (may Allah be pleased with him) narrates that a man who intended to travel came to the Messenger of Allah (peace and blessings be upon him) and said: O Messenger of Allah! Advise me. The Prophet (peace and blessings be upon him) said: "I advise you to fear Allah, and to say «اﷲ اكبر» at every elevated place."
