Indeed, those who lower their voices (in) presence (of the) Messenger (of) Allah - those, (are) the ones has tested Allah their hearts for righteousness. For them (is) forgiveness and a reward great.
On that Day they will follow the caller, no deviation from it. And (will be) humbled the voices for the Most Gracious, so not you will hear except a faint sound.
And be moderate in your pace and lower [of] your voice. Indeed, (the) harshest (of all) sounds (is) surely (the) voice (of) the donkeys."
And incite whoever you can among them with your voice, and assault [on] them with your cavalry and infantry and be a partner in the wealth and the children, and promise them." And not promises them the Shaitaan except delusion.
