From a Sermon of the Prophet Muhammad (peace be upon him).
‘Abdullah Ibn ‘Abbas may Allah be pleased with him, a companion of the Messenger of Allah (peace be upon him) said,
“O people! Indeed, livelihood has been decreed and no human will exceed what had been decreed for him; therefore, seek your livelihood with ease.
And the span of life is limited, no one can exceed what had been decreed for him; therefore, hasten without delay to do good deeds before life is over.
All deeds are computed, none will be forgotten, neither small nor big; therefore, commit many good deeds.
O people! Indeed, there is ease in moderation, and there is sufficiency in economization, and there is comfort in abstinence.
For every deed there is a reward.
Everything which is coming will be here very soon.”
