It is narrated from Hazrat Nu'man bin Bashir (may Allah be pleased with him) that the Holy Prophet (peace and blessings be upon him) once said from the pulpit: "He who does not thank for a little, does not thank for much. He who does not thank people, does not thank Allah. Mentioning the blessings and favors of Allah is gratitude; neglecting them is ingratitude. Unity is mercy and division is punishment."
