LOWERING ONE'S VOICE WHEN PROCLAIMING THE GREATNESS OF ALLAH H 992 "We were with the Prophet, praise and peace be upon him, on a journey and when we climbed a height we would loudly proclaim, 'There is no god except Allah, and Allah is Great!' The Prophet, praise and peace be upon him, admonished us, 'O people, do not exhaust yourselves. He on whom you call is neither deaf nor absent. He is with you, All Hearing and close.'" R 992 Bukhari and Muslim with a chain up to Abu Musa Ash'ari who related that the Messenger of Allah, praise and peace be upon him, said this.
979- وعن أَبي موسى الأشعريِّ رضي الله عنه ، قَالَ : كنّا مَعَ النبيِّ صلى الله عليه وآله وسلم في سَفَرٍ ، فَكُنَّا إِذَا أشْرَفْنَا عَلَى وَادٍ هَلَّلْنَا وَكَبَّرْنَا وَارتَفَعَتْ أصْوَاتُنَا ، فَقَالَ النبيُّ صلى الله عليه وآله وسلم : "يَا أيُّهَا النَّاسُ ، ارْبَعُوا عَلَى أنْفُسِكُمْ ، فَإنَّكُمْ لاَ تَدْعُونَ أصَمَّ وَلاَ غَائِباً ، إنَّهُ مَعَكُمْ ، إنَّهُ سَمِيعٌ قَرِيبٌ" متفقٌ عَلَيْهِ . " ارْبَعُوا" بفتحِ الباءِ الموحدةِ أيْ : ارْفُقُوا بِأَنْفُسِكُمْ .
