In his last will hazrath Ali (a.s) said…I advise you, and all my children, my relatives, and whosoever receives this message, to be conscious of Allah, to remove your differences, and to strengthen your ties. I heard your grandfather, peace be upon him, say: “Reconciliation of your differences is more worthy than all prayers and all fasting. Maintain communication and exchange of opinion among yourselves. Beware of disunity and enmity. Do not desist from promoting good deeds and cautioning against bad ones. Should you do that,the worst among you would be your leaders, and you will call upon Allah without response.
