Imam Hasan Askari (a.s) also lived a simplistic and abstemious existence. By way of testing, one day, the ruler caliph sent him lots of delicious foods and luxurious clothes. He gave away all of it in charity. Someone instigated the caliph that the Imam had not accorded any respect to the royal gifts and that he has squandered them all away.
The caliph became infuriated and summoned the Imam at once and said, “You have belittled the gifts I sent you and you gave them to the beggars thus insulting me.” The Imam said, “It is not so. We Ahl ul-Bayt of the Prophet, have forsaken the pleasures of the world. We are used to betake very simple food and wear patched clothes. Thus I gave it all to those who were deserving of it.” The caliph had no reply to this.
