Al-Lu'lu Wal-Marjan 626 — The Book of Zakât

Abu Sa'id al-Khudri Narrated from:

Once the Prophet ﷺ sat on the pulpit and we sat around him. Then he said, "The thing I am afraid of most for your sake (concerning what will befall you after me) is the pleasures and splendours of the world and its beauties which will be disclosed to you."Somebody said, "O Allâh's Messenger! Can the good bring forth evil? The Prophet ﷺ remained silent for a while. It was said to that person, "What is wrong with you? You are talking to the Prophet ﷺ while he is not talking to you." Then we noticed that he (the Prophet) was being inspired divinely. Then the Prophet ﷺ wiped off his sweat and said, "Where is the questioner?" It seemed as if the Prophet ﷺ liked his question.Then he said, "Good never brings forth evil. Indeed it is like what grows on the banks of a stream which either kills or make the animals sick, except if an animal eats its fill the Khadira (a kind of vegetation) and then faces the sun, starts ruminating and then passes out dung and urine and grazes again.No doubt this wealth is sweet and green. Blessed is the wealth of a Muslim from which he gives to the poor, the orphans and to needy travellers (or the Prophet ﷺ said something similar to it). No doubt, whoever takes it illegally will be like the one who eats but is never satisfied, and his wealth will be a witness against him on the Day of Resurrection."( Sahîh Al-Bukhârî, Hadîth No. 544, Vol. 2 )
