It is narrated from Sayyiduna Amr bin al-As (may Allah be pleased with him); he said: I said: "O Messenger of Allah, who among people is most beloved to you?" He (peace and blessings be upon him) said: "Why do you ask?" I said: "So that I too may love the one whom you love." He (peace and blessings be upon him) said: "Aishah."
