In the Name of Allah , the Compassionate , the Merciful
Imam Sadiq [a] said that the Messenger of Allah [s] gathered the children of 'Abd-il-Muttallib and said: "O' children of 'Abd-il-Muttallib! Initiate greetings, have regard for kinship, perform the night prayers while people are asleep, feed (others) food, and deliver good speech and thereby you will enter paradise in peace."
