Wahb bin Munabbih (RH) said:
A scholar once asked another greater than him in knowledge, “How much should I build?” He replied, “As much as shelters you from the sun and the rain.”
He asked, “How much food should I eat?” He replied, “More than what keeps you hungry and less than what makes you full.”
He asked, “How much should I wear?” He replied, “As the Messiah (Jesus) did.”
He asked, “How much should I laugh?” He replied, “As much as appears on your face but does not make audible your voice.”
He asked, “How much should I cry?” He replied, “Never tire from crying out of the fear of Allâh.”
He asked, “How much should I hide my deeds?” He replied, “Until people think you had not done a good deed.”
He asked, “How much should I make public my deeds?” He replied, “As much as will let the keen follow your example but not have the people talk about you.”

“Make the most of five things before five others: life before death, health before sickness, free time before becoming busy, youth before old age, and wealth before poverty.”
Imam Ahmad advised: Whatever good you are able to do then do it- perhaps you will not be able to tomorrow. And do not postpone today's deeds for tomorrow, perhaps tomorrow will come and you are deceased.
