Abu Hurairah, may Allah be pleased with them, said that: Allah's Messenger said: "They said: “O Messenger of Allah, whom should I treat kindly?' He said: “Your mother.' He said: “Then who?' He said : “Your mother." He said: “Then who?' He said: “Your father'. He said : “Then who?' He said: “The next closest and the next closest””””””””
