Be conscious and respectful when speaking in God's presence

This hadith speaks to the importance of being mindful when speaking in the presence of Allah. The Prophet Muhammad ﷺ was travelling with his companions during Hajj, and whenever they went up a high place they would call out "None has the right to be worshipped but Allah, and Allah is Greater". The Prophet ﷺ then reminded them that although it may seem like they are calling out to someone who cannot hear them, this is not true - for He is All-Hearer and ever Near. In other words, even though we may not see Him or feel His presence directly, He still hears us at all times. Therefore it is important for us to be conscious of our speech when speaking in His presence - for our words should reflect our respect for Him as well as our understanding that He can hear everything we say.
