"The strongest man is he who can control himself when he is angry"
He then asked,
"Who is a barren person?" They replied, "The one who is incapable of bearing offspring."
Rasulullah Sallallaho alaihe wasallam said, "No, it is the one who has not sent a child ahead of him to the Hereafter".
"He then asked, "Who is a destitute person?" They replied, "The one who has no property".
Rasulullah Sallallaho alaihe wasallam said, "The destitute person, and the utterly destitute, is he who possessed property but did not send anything ahead of him" (for the Day when his needs would be the greatest but he would be empty-handed).
