Once, Imam Sajjad (a.s.) encountered some lepers sitting on the roadside and eating their food. Greeting them, he passed by, when all of a sudden he stopped and said to himself:
“God does not like the haughty ones.”
Having said this, he retraced his steps and approaching the lepers, said, “Presently, I am in a state of fasting (and thus unable to sit down and share your food). (However) I invite you to come to my house and be my guests.”
They accepted the offer and went to his house, where the Imam (a.s.) fed them and helped them by giving them some money.( Baa Mardum In Guneh Barkhord Kuneem, pg. 38.)
