It is narrated from Sayyiduna Abd al-Muttalib bin Rabi'ah (may Allah be pleased with him) that Sayyiduna al-Abbas (may Allah be pleased with him) came to the Prophet (peace and blessings be upon him) and said: "O Messenger of Allah, Quraysh meet one another with cheerful faces, but treat us otherwise." Hearing this, the Messenger of Allah (peace and blessings be upon him) became angry until sweat appeared between his eyes, then he said: "No servant will taste the sweetness of faith until he loves you for the sake of Allah and His Messenger."
