Narrated Abu Musa: We were in the company of the Prophet on a journey, and whenever we ascended a high place, we used to say Takbir (in a loud voice). The Prophet said, "O people! Be kind to yourselves, for you are not calling upon a deaf or an absent one, but You are calling an All-Hearer, and an All-Seer." Then he came to me as I was reciting silently, "La haul a wala quwwata illa bil-lah." He said, "O `Abdullah bin Qais! Say: La haul a walaquwata illa bil-lah, for it is one of the treasures of Paradise." Or he said, "Shall I tell you a word which is one of the treasures of Paradise? It is: La haul a wala quwwata illa bil-lah."

Narrated Abu Musa Al-Ash`ari: We were in the company of Allah's Apostle (during Hajj). Whenever we went up a high place we used to say: "None has the right to be worshipped but Allah, and Allah is Greater," and our voices used to rise, so the Prophet said, "O people! Be merciful to yourselves (i.e. don't raise your voice), for you are not calling a deaf or an absent one, but One Who is with you, no doubt He is All-Hearer, ever Near (to all things).

Narrated Abu Musa Al-Ash`ari: The Prophet started ascending a high place or hill. A man (amongst his companions) ascended it and shouted in a loud voice, "La ilaha illal-lahu wallahu Akbar." (At that time) Allah's Apostle was riding his mule. Allah's Apostle said, "You are not calling upon a deaf or an absent one." and added, "O Abu Musa (or, O `Abdullah)! Shall I tell you a sentence from the treasure of Paradise?" I said, "Yes." He said, "La haul a wala quwwata illa billah,"

Narrated Abu Musa: We were with the Prophet on a journey, and whenever we ascended a high place, we used to say, "Allahu Akbar." The Prophet said, "Don't trouble yourselves too much! You are not calling a deaf or an absent person, but you are calling One Who Hears, Sees, and is very near." Then he came to me while I was saying in my heart, "La hawla wala quwwatta illa billah (There is neither might nor power but with Allah)." He said, to me, "O `Abdullah bin Qais! Say, 'La hawla wala quwwata illa billah (There is neither might nor power but with Allah), for it is one of the treasures of Paradise." Or said, "Shall I tell you of it?"
