Riyad as-Salihin — Hadith #46163

On the authority of Abu Musa Al-Ash’ari, may God be pleased with him, he said: We were with the Prophet, may God’s prayers and peace be upon him, on a journey. When we overlooked a valley, we would cheer and say “Allahu Akbar” and our voices would rise, so the Prophet, may God’s prayers and peace be upon him, said: “O people, be careful with yourselves, for you will not call on the deaf or the absent. He is with you. He is the Hearer and Near.” (Agreed upon) “Arba`a” with the opening of the unified ba’, meaning: be kind to yourselves.
